Description

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.
