START(END) ADDR - These addresses are used to specify the window size. It should be noted that when
the start address is greater than the end address, the window will be disabled.
WEN - Enable the window display.
WSHD - Enable shadowing on the window.
R, G, B - Specify the color of the relative background window.
2. Frame control registers,

VERTD
VERTD - Specify the starting position for vertical display. The total steps are 256, and the increment of each
step is 4 Horizontal display lines. The initial value is 4 after power up.

HORD
HORD - Define the starting position for horizontal display. The total steps are 256, and the increment of each
step is 6 dots. The initial value is 15 after power up.

CH6 CH5 CH4 CH3 CH2 CH1 CH0
CH6-CH0 - Define the character vertical height, the height is programmable from 18 to 71 lines. The character
vertical height is at least 18 lines if the contents of CH6-CH0 is less than 18. For example, when
the contents is " 2 ", the character vertical height is regarded as equal to 20 lines. And if the con-
tents of CH4-CH0 is greater than or equal to 18, it will be regarded as equal to 17. See Table 2
and Table 3 for detail description of this operation.
