Display Control Features and Characteristics
Display Control Command Structure
The display control commands, COMMAND0 to COM-
MAND5, are shifted in 8-bit serial units. The first byte of a
command consists of an identification code and data. The
second byte consists of data only. Once the command iden-
tification code in byte 1 has been written, it is saved until
the next time the first byte is written. If COMMAND1 is
written, the display character write mode begins and the
first byte does not change. When CS is HIGH, COM-
MAND0 is set.
