Set Data Auto Read
Auto Reset
This command is convenient for sending a full screen of data from the external display RAM. After
Setting Auto mode, a Data Write (or Read) command does not need sent between each datum. A Data
Auto Write (or Read) command must be sent after a Set Address Pointer command. After this
Command, the address pointer is automatically incremented by 1 after each datum. In Auto mode, the
RA6963 cannot accept any other commands.
The Auto Reset command must be sent to the RA6963 after all data has been sent, to clear Auto
Mode.
Note: A Status Check for Auto Mode
STA2, STA3 should be checked between sending of each datum. Auto Reset should be
performed after checking STA3=1 (STA2=1). Refer to the following flowchart.
