OF( value) Capture field 1 bit.
NONE 0 Do not capture field 1. Not used. Not used.
DEFAULT 1 Capture field 1. Not used. Not used.
FLDCAP
3-2 Reserved - 0 Reserved. The reserved bit location is always read as 0. A value written to this field
has no effect.
1-0 CMODE OF( value) 0-3h Capture mode select bit.
DEFAULT 0 Enables 8-bit BT.656 mode. Not used.
BT656B
RAWB 2h Enables 8-bit raw data mode. Not used.
The ERRFILT, STEN, and TCKEN bits may be written at any time. To ensure stable counter operation,
writes to the CTMODE bit are disabled unless the system time counter is halted (ENSTC = 0).
The transport stream interface capture control register (TCICTL) controls TCI capture operation. TCICTL
is shown in Figure 3-31 and described in Table 3-24 .
