VRTMG2~VRTMG0: Sets the number of lines per frame. Enabled only when VLINSEL in
VDOSELGT: Selects VD after noise rejection by VGATE (VD gate pulse) or VDIN as the signal output
VDOSEL: Selects VD generated by the internal V counter or VD selected by VDOSELGT as the signal
VGSTA: Selects the falling or rising edge of VDIN as the VGATE starting point.
REGF1: Forces serial byte processing (alternately outputs color difference signal and Y signal as 8-bit
REGF2: Sets the data between EAV and SAV.
ADCLAPO: Sets the polarity for clamp pulse.
CLPSTA10~CLPSTA4: Sets the starting point of the clamp pulse generated internally in Clamp

0 (default): Outputs VDIN unchanged.
1: Outputs VD after noise rejection by VGATE.
0 (default): Outputs VD selected by VDOSELGT.
1: Outputs VD generated by the internal V counter.
0 (default): Selects falling edge of VDIN as the VGATE starting point.
1: Selects rising edge of VDIN as the VGATE starting point.
0 (default): Performs serial byte processing only in R656 and R601 8-Bit Modes.
1: Forces serial byte processing to be performed.
0 (default): Sets data between EAV and SAV to be 80H (Cb or Cr) or 10H (Y).
1: Does not set data between EAV and SAV but outputs the input data unchanged.
0 (default): Inverts polarity.
Set to 0 if VDIN has positive polarity. Set to 1 if VDIN has negative polarity.

VRTMG1
Pulse Internal Generation Mode (i.e. when CLPSEL = 1 in Sub-Address 0EH).
This setting works in combination with the setting of CLPSTA3~CLPSTA0 in
