Data Read / Write
to D/C pin for 8080-series parallel mode. No data read is provided in serial interface mode.
no automatic increase will be performed in read-modify-write mode.
detail waveform diagram.
For serial interface mode, it is always in write mode. GDDRAM column address pointer will be increased by one automatically after each
data write.
The incrementation of the pointer stops at 131. Therefore there is a need to re-initialize the pointer when progress to another page ad-

To read data from the GDDRAM, input High to R/W(WR) pin and D/C pin for 6800-series parallel mode, Low to E(RD) pin and High
In normal data read mode, GDDRAM column address pointer will be increased by one automatically after each data read. However,
Also, a dummy read is required before first valid data is read. See Figure 3 on page 11 in Functional Block Descriptions section for
To write data to the GDDRAM, input Low to R/W(WR) pin and High to D/C pin for both 6800-series and 8080-series parallel mode.
It should be noted that, after the automatic column address increment, the pointer will NOT wrap round to 0 when overflow (>131).
