(5) Column start address Register
(Higher byte : Address 12h, default : 00h, R/W)
(Lower byte : Address 13h, default : 06h, R/W)
Define window start position column address of display window. Should be programmed with value
between 6 and 406.
(6) Window Height address Register
(Higher byte : Address 14h, default : 01h, R/W)
(Lower byte : Address 15h, default : 2Eh, R/W)
Define display window height. If you need smaller display window height, decrease the value.
Window end position row address = row start address + window height address –1
(7) Window width address Register
(Higher byte : Address 16h, default : 01h, R/W)
(Lower byte : Address 17h, default : 92h, R/W)
Define display window width. If you need smaller display window width, decrease the value.
Window end position column address = column start address + window width address -1
Note : Display window programming.
< Display Window Programming >
The 400*300 resolution chip can read any user specific window area within active window area.
This is called panning function. For this function, ‘row start’, ‘column start’, ‘width’, and ‘height’
can be programmed with four sets of register pair.
