5 Jumper Setting JP5: ICE/Stand-alone mode select If you short the With ICE positions, the clock source selection of is set by the configuration in ICE software. If you short the Stand-alone positions, the clock source selection of depends on the configuration of JP2, JP3 and S2 on the EVB. JP4: OSC select If you short the RC positions, the low frequency is generated from RC circuits. If you short the CRY positions, the low frequency is generated from oscillator circuits. JP6: OSCX select If you short the RC positions, the high frequency is generated from RC circuits. If you short the CRY positions, the high frequency is generated from Ceramic circuits. J10: Chip Power select If you short the V3V positions, the SH69V93 is powered by 3V source (provide from EVB). If you short the EXT positions, the power (2.4~3.6V, refer to SH67K93/90 spec.) of SH69V93 is input from external source, which connect to the VDD_EXT (JP3_31) directly. J12: Chip current test point. This jumper could be used to measure the operation current of EV chip (a litter bigger than SH67K93/90). If it s open, no power is provided for EV chip. J6: Bit 5: STACK OVER ON/OFF switch. The stack overflow function will on when it turned ON. J7: Reserved for test. Switch Setting: S2 (RESET): Reset the EVB when push the button. S1 (OPTION): 1.

Switch to 0 when the JP6 short the CRY position. 3. Bit3: LCD PUMP clock select 0: 4kHz. 1: 8kHz. 4. Bit4~5: Watch Dog option: 00: Watch Dog disable. 01 or 10:Watch Dog Enable but the WDT counter stops counting in stop mode. 11: Watch Dog always Enable 5. Bit 6:IC_TYPE select 0: Used as SH67K93 EVB. 1: Used as SH67K90 EVB. 6. Bit 7 (B0) and Bit8 (B1) are bonding option. Programmer can read the state of bonding option through the system register $2EH. 5

6 LED Declaration: Power indicate (Green): Power LED is lighted when EVB is powered. STOP indicate (Red): STOP LED is lighted when the CPU was in STOP mode. HALT indicate (Yellow): HALT LED is lighted when the CPU was in HALT mode. RICE66 Usage Notice: Evaluate your program with ICE indicate: 1. After entering to RICE66 and successfully downloading the user program, push the F5 (Reset) on PC keyboard before run your program when you evaluate your program with ICE. If there were abnormal response, the user should push the F5 key again until the ICE work normally. 2. First time run RICE66, need to select an appropriate MCU type, clock frequency... save the settings and restart RICE66 again. 3. Can t execute Step (F8) or Step over call (F9) while the ICE worked in HALT or STOP mode. 4. When you want to escape from HALT or STOP (in ICE mode), you should press the F5 key on PC keyboard twice. 5. The maximum current limit of the 3V power is 100mA, when the user uses internal 3V power to drive external device such as LED. 6. When EV Board worked in with ICE mode, you can input the clock from EXOSC_IN as the system clock. (Refer to the RICE66 User s Guide) 6

7 ROM bank switch Application Notice The PC (Program Counter) of 66xx can only address 4K ROM spaces. The SH67K93/90 chip uses the bank switch technique to extend its address space. The lower 2K of CPU addressing space, maps to the lower 2K of ROM (BANK0). The upper 2K of CPU addressing space maps to one of 1 banks (BANK1~11) of the upper 22K ROM in SH67K93/90. (See the Details in spec.) Bank switch program example: Example 1: Description: Jump from BANK0 to BANK2 Program Code: BANK EQU 1FH ; define the system register BANK2 EQU 01H ; define the constant ORG 0000H ; BANK0 program... LDI IE,00H ; must disable the IE before the bank switch option LDI BANK, BANK2 ; write the system register to switch bank JMP 1000H ; from BANK0 jump to BANK ORG 1000H ; BANK2 program LDI IE, 0xH ; recover the IE... Example 2: Description: Jump from BANK1 to BANK4 Program Code: BANK EQU 1FH ; define the system register BANK4 EQU 03H ; define the constant ORG 0800H ; BANK1 program... LDI IE,00H ; must disable the IE before the bank switch option LDI BANK, BANK4 ; write the system register to switch bank JMP B4SR1 ; from BANK1 jump to BANK ORG 2000H ; BANK4 program... B4SR1: LDI IE, 0Xh ; recover the IE... 7

8 Programming Notices 1. Clear data RAM and initialize all system registers at the beginning. 2. Do not perform logical operation with I/O ports (such as ANDIM EORIM). Especially when the I/O ports have external connections. 3. Do not perform arithmetic operation with those registers only have 1, 2 or 3 bits. This kind of operation may not get the result you expected. 4. Never use reserved registers. 5. It is necessary to add NOP before and after the HALT instruction, else the CPU will execute error instruction when it wakes up from the HALT.... NOP HALT NOP It is wise to set the Interrupt Enable flag before you return from subroutine in two instructions.... LDI IE, 04H ; Enable timer0 interrupt LDA Temp,0 RTNI 7. When you set the Interrupt enable flag as the following and your subroutine not be set Interrupt Enable flag, then your system will never wake up if an interrupt entered between the NOP instruction.... LDI IE, 1111B ; IE = Interrupt enable flag NOP NOP NOP HALT To add LIST P=67K93 or romsize = xxxx at the beginning of a program. If found problem in compiling the program. Check if the NT6566.dev is located at the RICE66 program directory. 9. Please disable any interrupt before switching Bank. (See the Bank switch program example at the previous page) 10. When PortB share as CallerID interface, PortB.3 has no share function, so it is also could be used as general I/O port, but interrupt function of PortB.3 is disable. 11. When PA.0 use as INT0 source, pull high or Pull low must enable.( set PA0_PEN =1). Otherwise the INT0 can t be respond. 12. If DTMF decoder is needed, after DTMF decode flag is enable and waiting for finished flag, if a jump instruction is executed, the jump object address low 7 bits is , then a read-change-write instruction is consequently executed(such as andim, eorim etc.), In these case, the DTMF decode would go to error, so if your program in case of all these condition, NOP instruction should be added before that read-change-write instruction. 13. When stop instruction is executed. LCD PUMP ($13.3) will auto be disable, but LCD ON control bit ($13.2) will keep the state. So if you want to get Lower power consumption in stop state, you d better to shut down LCD by write 0 to LCD ON control bit($13.2). 14. It takes at most 5 ms for the OSCX oscillation circuit to go on until the oscillation stabilizes in sh67k93, and this time maybe became 20~30 ms in sh67p93. So when switching the CPU system clock from OSC to OSCX, one must wait at least 5ms (sh67k93) or 30ms (sh67p93) from the OSCX oscillation is turn on. However, the start time varies a lot with respect to oscillator characteristics and operational conditions. Therefore the waiting time depends on applications. 15. Because the power structure between SH67P93 and SH67K93 has a little difference, the LCD contrast setting is difference as following: 15.1 If the system is High Frequency clock and is not in HALT mode, the LCD contrast level of SH67P93 will be added 1 or 2 steps based on the SH67K For the other conditions, the difference does not exist. 8

9 Usage of CID Linking Tool: For the CID application, after assembling and linking the user s source file (*.asm), the output file (*.obj) will be created without CID decoder code. You need to create the final file (*.obj) using this CID linking tool. The CID Decoder Linking Tool (v0.1) is a PC program which links the CID decoder code (*.obj, provided by SinoWealth Corp.) to the user s application code (*.obj, created by user) for SH67K93/90 (SH69V93) and SH67K93/K90 (SH67V93/V90). Also, it provides the interface to adjust the parameters for your special application. When running the program, the interface is like the figure shown below: DTMF Parameters Panel: Parameters to adjust the DTMF decode effect FSK Gain Panel: Parameters to adjust the FSK decode effect CAS Parameters Panel: Parameters to adjust the CAS detect effect Part No. Selection Panel: Selection correct IC type for the application Customer Main File: The user s application code selection panel CID Decoder File: The CID decoder code selection panel Linked File (Customer + CID): The output file which the tool creates. Fig 8. Link tools For the CID application of SH67K93/90 (SH69V93), these parameters are available to improve the CID decode performance: Sum1/ H1/ L1, Sum3/ H3/ L3 (DTMF Parameters): Affect the performance of the DTMF S/N. You can set the value between 0x0000 and 0xFFFF. Gain(04 Set Wakeup Parameters): The configuration of 04 Set wakeup gain. You can set the value between 0 and F. Trigger Window(04 Set Wakeup Parameters): The configuration of 04 Set wakeup threshold voltage. You can set the value between 0 and 3. TYP I &TYP II(FSK Gain): Affect the performance of the FSK decodes. You can set the value between 0 and F. CAS Parameters(CAS Decoder Parameters): Affect the performance of the Cas decodes. You can set the value between 0x0000 and 0XFFFF. Gain (Cas Parameters): Affect the performance of the Cas decodes. You can set the value between 0 and F. 9

10 Example: Files: UserCode.obj The user s application code, assembled and linked by user. CID_Code.obj The CID decode code, provide by SinoWealth Corp. 1. Run the CID Link Tool on your PC.(see Fig 8) 2. Click the SH67K93/90 radio selection to choose the correct IC. Then click the button on the pop-up dialog to confirm. 3. Click the <Browse> button on the Customer Main File panel, choose the Customer file (*.obj) that you created. 10

11 4. Click the <Browse> button on the CID Decoder File panel, choose the CID decoder file (*.obj). 5. After Selecting the correct Customer and CID code, the parameters that you used last time, will display on the interface. You can modify the value to improve the CID decoder performance. 11

12 6. You can also specify the output file by clicking the <Browse> button on the Link File (Customer Main File + CID Decoder File) panel. Otherwise, the program will overwrite the customer file by default. 7. After you confirm all the setting and selection, click on the <Link> button. The program will give you the prompt If linking successfully. 8. The final code (*.obj) is created in the directory that you specified. You can continue to debug or release your final code. 12

13 CAS parameter adjustment: 1. There are 13 parameter could be adjustable in CAS performance optimizes. CAS-AGC: set the gain of CAS AMP. CAS-SUM1/H1/L1: CAS-SUM3/H3/L3: CAS-S5/H5/L5: (0002H/0008H/0001H are recommend) CAS-S16/H16/L16: (0070H/0080H/0080H are recommend) The first parameter is set for hardware AMP gain. The others are set for CAS decode algorithm, The more of these 12 parameter is big, the more critical for CAS signal confirm. The first six parameters (CAS-SUM1/H1/L1 CAS-SUM3/H3/L3) are sensitive in CAS Detect, and the other six parameters are not, so the default value is recommended. There are three aspects about CAS performance: 1) Signal recognition,2) Talkdown performance and 3) Talkoff performance. When you optimize CAS detect performance, at first, you should adjust the CAS-SUM1/H1/L1 CAS-SUM3/H3/L3 to adopt the Signal recognition requirement (according to SUM3->H3->L3->SUM1->H1->L1 sequence). Then go on the Talkdown and Talkoff test, If your CPE can t pass Talkdown test, decrease those six parameters a litter, at the same time, Signal recognition test must be guaranteed pass. And if your CPE can t pass Takeoff test, increase those six parameters a litter, and Signal recognition test also should be guaranteed pass. Note: Anti-sidetone circuit should be used to provide the CAS signal in sh67k93, if anti-sidetone circuit could provide 20db SNR for CAS signal, the sh67k93 could get a better performance in Talkdown and Talkoff test. 13
