Data Read / Write
To read data from the GDDRAM, input High to R/W pin and D/C pin. Data is valid at the falling edge of CS. And the GDDRAM column
address pointer will be increasd by one automatically.
To write data to the GDDRAM, input Low to R/W pin and High to D/C pin. Data is latched at the falling edge of CS. And the GDDRAM column
address pointer will be increasd by one automatically.
No auto address pointer increment will be performed for the Dummy Write Data after Master Clear GDDRAM. (Refer to the “Commands
Required for R/W Actions on RAM” Table)

*2
Address Increment is done automatically data read write. The column address pointer of GDDRAM*3 is affected.
Remarks : *1. Refer to the command “Read Contrast Vaule”.
*2. If write data is issued after Command Clear RAM, Address increse is not applied.
*3. Column Address will be wrapped round when overflow.
