8bits data from SRAM
Write/Read Data Byte ( command 1,2 ) operations access display buffer RAM based on Page Address (PA)
register and Column Address (CA) register. To minimize bus interface cycles, PA and CA will be
incremented automatically depending on the setting of Access Control (AC) registers. PA and CA can also
be programmed directly by issuing
Set Page Address
and
Set Column Address
commands.
If Wrap-Around (WA) is OFF (AC[0] = 0), CA will stop increasing after reaching the end of page (MC), and
system programmers need to set the values of PA and CA explicitly. If WA is ON (AC[0]=1), when CA
reaches end of page, CA will be reset to 0 and PA will be increased or decrease by 1, depending on the
setting of Page Increment Direction (PID, AC[2]). When PA reaches the boundary of RAM (i.e. PA = 0 or 15),
PA will be wrapped around to the other end of RAM and continue.

Status flag definitions:
BZ
: Busy with internal process. When BZ=1 host interface can access if RS=0.
MX
: Status of register LC[1], mirror X.
DE
: Display enable flag. DE=1 when display enabled
RS
: Reset in progress. If RS=1.host interface will be inaccessible.
