NAME AND DESCRIPTION
RMF
SR2.7
Receive CAS Multiframe. Set every 2 ms (regardless if CAS
signaling is enabled or not) on receive multiframe boundaries.
Used to alert the host that signaling data is available.
RAF
SR2.6
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.
TMF
SR2.5
Transmit Multiframe. Set every 2 ms (regardless if CRC4 is
enabled) on transmit multiframe boundaries. Used to alert the
host that signaling data needs to be updated.
SEC
SR2.4
One-Second Timer. Set on increments of 1 second based on
RCLK.
TAF
SR2.3
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.
LOTC
SR2.2
Loss of Transmit Clock. Set when the TCLK pin has not
transitioned for one channel time (or 3.9
s). Will force pin 34
high if enabled via TCR2.0. Based on RCLK.
RCMF
SR2.1
Receive
CRC4
Multiframe.
Set
on
CRC4
multiframe
boundaries; will continue to be set every 2 ms on an arbitrary
boundary if CRC4 is disabled.
LORC
SR2.0
Loss of Receive Clock. Set when the RCLK pin has not
transitioned for at least 2
s (3 s ±1 s).
