Bit

field

symval

Value

BT.656, Y/C Mode,
or Raw Data Mode

TSI Mode

31–6

Reserved

0

Reserved. The reserved bit location is always read as 0. A value
written to this field has no effect.

5

ENSTC

System time clock enable bit.

HALTED

0

Not used.

System time clock input is disabled (to
save power). The system time clock
counters and tick counter do not increment.

CLKED

1

Not used.

System time input is enabled. The system
time clock counters and tick counters are
incremented by STCLK.

4

TCKEN

Tick count interrupt enable bit.

DISABLE

0

Not used.

Setting of the TICK bit is disabled.

SET

1

Not used.

The TICK bit in VPIS is set whenever the
tick count is reached.

3

STEN

System time clock interrupt enable bit.

DISABLE

0

Not used.

Setting of the STC bit is disabled.

SET

1

Not used.

A valid STC compare sets the STC bit in
VPIS.

2

CTMODE

Counter mode select bit.

90KHZ

0

Not used.

The 33-bit PCR portion of the system time
counter increments at 90 kHz (when PCRE
rolls over from 299 to 0).

STCLK

1

Not used.

The 33-bit PCR portion of the system time
counter increments by the STCLK input.

1

ERRFILT

Error filtering enable bit.

ACCEPT

0

Not used.

Packets with errors are received and the
PERR bit is set in the timestamp inserted at
the end of the packet.

REJECT

Packets with errors are filtered out (not
received in the FIFO).

0

Reserved
