The LH155BA has a lot of commands, as shown in
the list of commands, and each command is
explained in detail as follows.
Data codes and command codes are defined as
follows and the execution of commands must be
made in the chip selection state (CSB = "L").
(For example X address)

Command Codes
* RS = "0" : RAM data access (Refer to
Sections 4.2. and 4.3.
.)
RS = "1" : Register access (Refer to
Sections 4.4. through 4.17.
.)
The undefined command codes are inhibited.
The display RAM data of 8-bit are written in the
designated X and Y addresses.
4.2. Data Write to Display RAM

Immediately after data are set in X and Y
addresses, dummy read is necessary one time.
