FUNCTION NAME
This bit disables the DC-restore clamp for composite
Channel B.
0: Composite A clamp enabled
1: Composite A clamp disabled
This bit disables the DC-restore clamp for the luma (Y)
of S-Video Channel B.
Disables the 1µA pull-down currents for both Y and C.
Does not disable the clamp for chroma channel unless
in Slave mode and Sync Separator. B = 0x25.
0: S-Video A clamp enabled
1: S-Video A clamp disabled
This bit disables the DC-restore clamp for Y/G of
component Channel B.
Disables the 1µA pull-down currents for ALL three
channels.
Does not disable the pull-up clamp for Pr/R and Pb/B
unless in Slave mode AND Sync Separator. B = 0x24.
0: Y Component A clamp enabled
1: Y Component A clamp disabled
0: Normal operation
1: DC-restore clamp has a lower offset.
Slightly lowers the DC offset of the component outputs
by increasing the maximum amount of clamp restore
current from 250µA to 500µA.
This bit disables the DC-restore clamp for composite
Channel A
0: Composite A clamp enabled
1: Composite A clamp disabled
This bit disables the DC-restore clamp for the luma (Y)
of S-Video Channel A.
Disables the 1µA pull-down currents for both Y and C.
Does not disable the clamp for chroma channel unless
in Slave mode and Sync Separator. A = 0x25.
0: S-Video A clamp enabled
1: S-Video A clamp disabled
This bit disables the DC-restore clamp for Y/G of
component Channel A.
Disables the 1µA pull-down currents for ALL three
channels.
Does not disable the clamps for Pr/R and Pb/B unless
in Slave mode AND Sync Separator. A = 0x24.
0: Y Component A clamp enabled
1: Y Component A clamp disabled
0: Normal operation
1: DC-restore clamp has a lower offset.
Slightly lowers the DC offset of the component outputs
by increasing the maximum amount of clamp restore
current from 250µA to 500µA.
