I
: Begins the H-Freq count. To read the value in the H-Freq registers, the write command (Reg0)
needs to be issued first.
: The status of polarity, presence and static level for HS and VS.
: Hfreq Count Finish flags, Hfreq high bit.
: Selects the source of VBLANK and controls the polarity status of H pol, V pol
1. H pol , V pol
2. HS pre , VS pre , HVpre
3. H sl , V sl
* HVpre represents the status of the composite (H/V) presence in HS. H sl or V sl is valid only
1. HCFF
2. HF10 - HF8
and SYNC output polarity.
1. HV cvs
2. HB pl = 1 -> negative HBLANK output,
3. VB pl = 1 -> negative VBLANK output,
* After power-on, HB pl and VB pl shall be initialized to 0.
4. H pf1 , H pf0 = 0,0 or 1,1
5. V pf1 , V pf0
when HS pre or VS pre is not present.
