1 For Loop Example: for(j=0; j<0; j++) { // do something } Loop: cmpa #0 ; Compare j to 0 bge EndLoop ; Else!(j<0) adda # ; Increment j How do we determine these values? Programming Steps:. Initialize J 2. Compare J to 0. If Not Less than 0,. End Loop 4. Else. do something 2. Increment J. Repeat Loop (Step 2) Loop: cmpa #0 ; Compare j to 0 bge EndLoop ; Else!(j<0) adda # ; Increment j 0A 04 0 Compare Value 0 BGE (Branch if greater then or equal to 0) 2 HCS2 Instruction Set Summary Overview HCS2 Instruction Glossary 4

3 HCS2 Registers - Accumulators HCS2 Registers - Accumulators Accumulators Source and destination of arithmetic operations A, B are 8-bit registers D is the combination of A and B Forms a 6-bit register A is the MSB and B is the LSB Used for 6-bit operations Is there any difference between the following assembly code examples? ldaa #50 ldab #0 ldaa # ldab #0A vs. ldd #050 vs. ldd #500 vs. ldd #0 vs. clra ldab #0A 9 0 HCS2 Registers - CCR Condition Code Register (CCR) C Carry/Borrow Set when a carry occurs during addition or a borrow occurs during subtraction V Overflow Set in the event of an overflow during an arithmetic operation Z Zero Set when all the bits of the result are 0s HCS2 Registers - CCR Condition Code Register (CCR) S Enable/Disable STOP instruction Clearing the S bit enables the STOP instruction Setting the S bit will treat a STOP instruction like a NOP I, X Mask IRQ/XIRQ Interrupts More on these later N Negative Shows the state of the MSB of the result N is most commonly used in two s complement arithmetic (more on this later) H Half Carry Indicates a carry from accumulator A bit during an addition operation DAA instruction uses the value of the H bit 2
