This register contains the settings for selecting either a hardware or soft-
ware slice level and for setting the data capture format. When you do not
use a bit or field in this register, tie it to the setting indicated below.
FCPSEL: Hard/soft sampling start position select
0: Select hardware calculation
1: Select software setting (set in SFTSTAP[10:0] field of STAP)
SYNCSEL: Sync signal select (HSYNC/VSYNC)
Tie this bit to 0.
HCNTSEL[1:0]: HSYNC count value select
When this field is unused, tie it to b'00'.
00: When odd, add 1 to the HSYNC count value
01: When even, add 1 to the HSYNC count value
10: No change to the HSYNC count value
11: Reserved
SLICESEL: Hard/soft slice level select

SLPULSEL: Polarity select for the CRI cycle transition detection
0: Detect 0 to 1 transitions
1: Detect 1 to 0 transitions
CRICSEL: Detection interval select for the CRI frequency width
0: CRI capture interval only
1: CRI capture interval and transition detection interval
NCRIGSEL: Sampling pulse generation interval
0: Disable the CRI capture interval
1: Enable the CRI capture interval
CNTSTAP[4:0]: Caption data sampling start position
The higher the setting in this field, the later the start position. The valid
range is x'00' to x'1F'.
