This command is convenient to send full screen data from external display RAM. After setting auto mode, "Data write
(or read)" command is not necessary between each data. "Data auto write (or read)" command should follow the "Address
pointer set" and address pointer is automatically increment by + 1 after each data. After sending (or receiving) all data "Auto
reset" is necessary to return normal operation because all data is regarded "Display data" and no command can be accepted in
the auto mode.
Note : Status check for auto mode (STA2,STA3) should be checked between each data. Auto reset should be performed after
checking STA3=1 (STA2=1). Please refer following flow chart.
