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
