Read Status Byte (
An 8 bits status byte will be placed onto the data bus when a read operation is performed if D/ C is low. The status
byte is defined as follows:

BUSY ON RES MF

Data Read / Write (
Low to E( RD ) pin and High to D/ C pin for 8080-series parallel mode. No data read is provided for serial mode. In
normal mode, GDDRAM column address pointer will be increased by one automatically after each data read. Also, a
dummy read is required before the first data is read. See
To write data to the GDDRAM, input Low to R/ W ( WR ) pin and High to D/ C pin for 6800-series parallel mode. For
serial interface, it will always be in write mode. GDDRAM column address pointer will be increased by one
automatically after each data write. The address will be reset to 0 in execution of next data read/write operation when
it is 127.
