Receive CAS Multiframe
. Set every 2ms (regardless if CAS signaling is
enabled or not) on receive multiframe boundaries.
Receive Align Frame.
Set every 250 s at the beginning of align frames.
Used to alert the host that Si and Sa bits are available in the RAF and
RNAF registers.
Transmit Multiframe.
Set every 2ms (regardless if CRC4 is enabled) on
transmit multiframe boundaries.
One-Second Timer.
Set on increments of one second based on RCLK. If
CCR2.7 = 1, this bit is set every 62.5ms instead of once a second.
Transmit Align Frame.
Set every 250 s at the beginning of align frames.
Used to alert the host that the TAF and TNAF registers need to be
updated.
Loss-of-Transmit Clock.
Set when the TCLK pin has not transitioned for
one channel time (or 3.9ms).
Receive CRC4 Multiframe.
Set on CRC4 multiframe boundaries;
continues to be set every 2ms on an arbitrary boundary if CRC4 is
disabled.
Pseudorandom Bit-Sequence Detect.
When receive PRBS is enabled,
this bit is set when the 2
15
- 1 PRBS pattern is detected at RTIP and
RRING. The PRBS pattern can be framed, unframed, or in a specific time
slot.
