Software Reset
0 = Normal operation.
1 = Reset all serial programming registers to their default values.
FIELD_ID
Enable SECAM Bottleneck Pulses
0 = Suppress SECAM field synchronization signal.
1 = Enable SECAM synchronization signal (bottleneck pulses).
CVBSD_INV
Invert CVBS_DLY Outputs
0 = Normal operation.
1 = Invert CVBS_DLY video output on DACs with CVBS_DLY selected.

AUTO_CHK
Automatic Monitor Status Checking
0 = Set the connection status bits (MONSTAT_A through MONSTAT_F) by writing to the
CHECK_STAT bit.
1 = Check the connection status bits once per frame during the vertical blanking interval.
CHECK_STAT
SLEEP
Manual Monitor Status Checking
Writing a 1 to this bit checks the connection status of the DACs. This is also automatically
performed on any reset condition. This bit is automatically cleared.
Sleep
0 = Normal operation.
1 = Sleep mode. Power down all components except serial interface and PLL. System clock
must be applied to wake up part.
