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 - 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.

HORR - Specify the resolution of a horizontal display line, and the increment of each step is 12 dots. That is,

the pixels' number per H line equal to HORR*12. It is recommended that HORR should be greater

than or equal to 36 and smaller than 90M / (Hfreq*12). The initial value is 40 after power up.

RSPACE - Define the row to row spacing in unit of horizontal line. That is, extra RSPACE horizontal lines will

be appended below each display row, and the maximum space is 31 lines. The initial value is 0

after power up.

Column 17 OSDEN BSEN SHADOW TRIC BLANK WENCLR RAMCLR FBKGC

OSDEN - Activate the OSD operation when this bit is set to "1". The initial value is 0 after power up.

BSEN - Enable the bordering and shadowing effect.

SHADOW - Activate the shadowing effect if this bit is set, otherwise the bordering is chosen.

TRIC - Define the driving state of output pins ROUT, GOUT, BOUT and FBKG when OSD is disabled. That is,

while OSD is disabled, these four pins will drive low if this bit is set to 1, otherwise these four pins are

in high impedance state. The initial value is 0 after power up.

BLANK - Force the FBKG pin output to high while this bit is set to "1".

WENCLR - Clear all WEN bits of window control registers when this bit is set to "1". The initial value is 0 after

power up.

RAMCLR - Clear all ADDRESS bytes of display registers when this bit is set to "1". The initial value is 0 after

power up.
