(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.
