Datasheet
○ Write display data and transfer method
This device has Display Data RAM (DDRAM) of 28×4=112bit.
The relationship between data input and display data, DDRAM data and address are as follows.

Display RAM data
According to this command, an 8-bit binary data will be written to the DDRAM. The starting address of the DDRAM where
data will be written is specified by “ADSET” command, and is automatically incremented for every 4 bits of data received..
Writing data to DDRAM can be done by continuously sending data.
(In case data is sent continuously after write date at 1Ah (SEG26), RAM data will be written to 1Bh (dummy address)
and return to address 00h (SEG0) automatically.)
In case SEG port assigned to GPO port by OUTSET command, corresponding SEG address do not change and used as
dummy address.

Display data write to DDRAM every 4 bits.
In case CSB changes from ”L” to ”H” before 4 bits of data transfer was finished, RAM write is cancelled.
