10 Version 1 Page 1 8.Function Description MODEL NO : ASI-_-22DS-KJ-_YD/X The LCD display Module is built in a LSI controller, the controller has two 8-bit registers, an instruction register (IR) and a data register (DR). The IR stores instruction codes, such as display clear and cursor shift, and address information for display data RAM (DDRAM) and character generator (CGRAM). The IR can only be written from the MPU. The DR temporarily stores data to be written or read from DDRAM or CGRAM. When address information is written into the IR, then data is stored into the DR from DDRAM or CGRAM. By the register selector (RS) signal, these two registers can be selected. RS R/W Operation IR write as an internal operation (display clear, etc.) 1 Read busy flag (DB7) and address counter (DB to DB7) 1 Write data to DDRAM or CGRAM (DR to DDRAM or CGRAM) 1 1 Read data from DDRAM or CGRAM (DDRAM or CGRAM to DR) Busy Flag (BF) When the busy flag is 1, the controller LSI is in the internal operation mode, and the next instruction will not be accepted. When RS= and R/W=1, the busy flag is output to DB7. The next instruction must be written after ensuring that the busy flag is. Address Counter (AC) The address counter (AC) assigns addresses to both DDRAM and CGRAM Display Data RAM (DDRAM) This DDRAM is used to store the display data represented in 8-bit character codes. Its extended capacity is 8 8 bits or 8 characters. Below figure is the relationship between DDRAM addresses and positions on the liquid crystal display. High bits Low bits Example: DDRAM addresses AC (hexadecimal) AC6 AC5 AC4 AC3 AC2 AC1 AC All Shore Industries, Inc. One Edgewater Plaza, Staten Island, NY 135

See Table 2. Character Generator RAM (CGRAM) In CGRAM, the user can rewrite character by program. For 5 8 dots, eight character patterns can be written, and for 5 1 dots, four character patterns can be written. Write into DDRAM the character code at the addresses shown as the left column of table 1. To show the character patterns stored in CGRAM. All Shore Industries, Inc.
