START
R/W
0h
This bit will start the operation of encoder.
0: encoder is in standby mode.. no data and signals will be outputted
1: encoder is in the normal operation mode.
During the normal operation, this bit should be kept at 1. Normally
software will set the bit whenever the operation needs to be started.

JED
R/W
0h
This bit can enable the JEIDA output format
0: DVO will output data in normal format
1: DVO will output data in JEIDA format
The JEIDA format is used to interface certain LCD panels. It is used
in RGB discrete sync mode only.

S_422
R/W
0h
When the DVO output is in 4:2:2 YCbCr format, this bit controls the
CbCr format.
0: The CBCR data is generated by a 444-to422- decimation filter.
1: The CBCR data are captured by every-other pixel. (skip one pixel
at a time)
