Address:
VPOL — Vsync Input Polarity
HPOL —þHsync Input Polarity
VSYNCS — VSYNC Input State
HSYNCS — HSYNC Input State
Reset:
Read: VSYNCS HSYNCS
Write:
This bit indicates the polarity of the VSYNC input, or the extracted
Vsync from a composite sync input (COMP=1). Reset clears this bit.
This bit indicates the polarity of the HSYNC input. This bit equals the
VPOL bit when the COMP bit is set. Reset clears this bit.
This read-only bit reflects the logical state of the VSYNC input.
This read-only bit reflects the logical state of the HSYNC input.
ATPOL
1 = Vsync is positive polarity
0 = Vsync is negative polarity
1 = Hsync is positive polarity
0 = Hsync is negative polarity
