S1D2502B01 VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS
26
Preliminary
The purpose of bits 'HPOL', and 'VPOL' is to provide flexibility when using the S1D2502B01 IC. No matter which
polarity you choose for the input signal, the IC will handle them identically, so you can select active high or active
low according to your convenience.

HPOL
(Bit B)
Polarity of horizontal fly back signal
If this bit is '1', HFLB's polarity is positive, and if '0', it is negative. In other
words, this bit is set to '1' if active high, and '0' if active low.
Polarity of vertical fly back signal
If this bit is '1', VFLB's polarity is positive, and if '0', it is negative. In other
words, this bit is set to '1' if active high, and '0' if active low.
Fade-in and fade-out time control
If this bit is '1', fade-in/fade-out time is 0.5sec. If not, it is 1sec.
Fade-in and fade-out enable
This feature is enabled when this bit is '1'. The effect where the display
goes from the center to the outside, or from the outside to the center in
units of font, is called fade-in/fade-out. Refer to fade-in/fade-out. You must
remember that fade-in/fade-out, like scrolling on/off, only occurs when OSD
enabled/disabled.
