ACC reference level to adjust C
A value of 0 disables the ACC, chroma gain can be adjusted via
ACCb / ACCr register. The setting is updated when ’sdt’ register is
updated.
ACC multiplier value for SECAM Db chroma component to adjust
C
updated.
b [10:0] eeemmmmmmmm
ACC multiplier value for SECAM Dr chroma component to adjust C
level on picture bus. The setting is updated when ’sdt’ register is
updated.

amplitude killer level (0: killer disabled)
amplitude killer hysteresis
NTSC tint angle, $512 = $ /4
crystal oscillator center frequency adjust, –2048 ... 2047
crystal oscillator center frequency adjustment value for line-locked
mode, true adjust value is DVCO – ADJUST.
For factory crystal alignment, using standard video signal:
set DVCO = 0, set lock mode, read crystal offset from ADJUST
register and use negative value for initial center frequency adjust-
ment via DVCO.
