data access returning to pre-set start column address once overflow (> end column address).

The page address will be incremented by column address overflow. The start column address,

end column address, start page address and end page address should set to 0,127,0,15

respectively before disable DMA mode.

Enable DMA mode (F4H, 05H)

Set Start/End Column and Page address

e.g. 84H, 10H, 01H, 60H, 0CH

(start column address = 16, start page address = 1,

end column address = 96, end page address = 12)

Set page and column address

e.g. B1H, 11H, 00H

(page address = 1, column address = 16)

Available write the data to GDDRAM

Disable DMA mode (F4H, 01H)

Reset Start/End Column and Page address

e.g. 84H, 00H, 00H, 7FH, 0FH

(start column address = 0, start page address = 0,

end column address = 127, end page address = 15)
