Address Increment Table (Automatic)
Address increment is done automatically data read write. The column address pointer of BGDRAM*3 is affected.

To read data from the BGDRAM, input high to RW pin and DCOM pin. Data is valid at the falling edge of CS. And the
BGDRAM column address pointer will be increased by one automatically.
To write data to the BGDRAM, input low to RW pin and high to DCOM pin. Data is latched at the falling edge of CS.
And the BGDRAM column address pointer will be increased by one automatically.
No auto address pointer increment will be performed for the dummy write data after ²master clear BGDRAM²
²*1² Refer to the command read contrast value
²*2² If write data is issued after command clear RAM, address increase is not applied
²*3² Column address will be wrapped around when overflow
²*1² Required only if desired status differ from power on reset
²*2² Effective only if internal contrast control is enabled.
²*3² Effective only if the regulator is enabled.
