Note 1) Adjust VREG1OUT and VCM0-4 to set VcomH the same level as VDH or less.
Note 2) Adjust VREG1OUT and VDV0-4 to set the amplitude of Vcom 6.0V or less.
RAM Address Set (R21h)
AD15–0:
Make the initial setting for the GRAM address in the address counter (AC). After GRAM data
are written, the address counter is automatically updated according to the settings with AM, I/D bits and the
setting for a new GRAM address is not required in the address counter. Therefore, data are written
consecutively without resetting the address. The address counter is not automatically updated when data
are read out from GRAM.
GRAM address setting can not be made during the standby mode. An address set should be made within
the area specified with the window address.
When the RGB interface is selected (RM = 1), the setting of the address for AD15-0 is made every frame at
the falling edge of VSYNC. When the internal clock operation or VSYNC interface is selected (RM = 0),
the setting of the address is made when the instruction is executed.
