Write mode 2: AM = 1, LG2-0 = “000”
This mode is used when the data is vertically written at high speed. It can also be used to initialize the
GRAM, develop the font pattern in the vertical direction, or draw borders. The write-data mask
function ( WM15-0 ) are also enabled in these operations. After writing, the address counter ( AC )
automatically increments by 256, and automatically jumps to the upper-right edge ( I/D =1 ) or upper-
left egde ( I/D = 0 ) following the I/D bit after it has reached the lower edge of the GRAM.

Notes: 1. The bit area data in the GRAM indicated by (*) is not changed.
2. After writing to address "AF00"H the AC jumps to "0001"H.
Operation Examples:
1) I/D = "1" , AM = "1", LG2-0 = "000"
2) WM15-0 = "07FF"H
3) AC = "0000"H
