These parameters are needed only when the VRST input is used.
VRSTN
The line number gets reset to this value on a negative edge of VRST. Default is 004h.
VRSTDY
Logic high denotes VRST will be delayed with respect to the line position. Default = 0 (no delay).
VRSTFLD
Logic high denotes the field is reset to even on a negative edge of VRST, logic low denotes the
field is reset to odd. Default = 0.

If the user chooses to limit the exposure time, the max shutter gain is set to this value. 00h=full
exposure, BFh=min exposure for NTSC, C4h= min exposure for PAL.

Logic high disables the black level loop. Black level remains at the current value. Default =0.
Analog-to-digital converter option. When written to a logic high, calibration is immediately en-
tered. This bit goes back low when calibration is complete.
Analog-to-digital converter option. Logic high results in calibration being done after every frame,
logic low results in calibration only on power up. Default = 0.
Logic high sets the frequency of HCLK to 16×the line frequency, logic low sets HCLK to 1×the
line frequency. Default = 0.
