NAME AND DESCRIPTION
RMF
SR2.7
Receive CAS Multiframe. Set every 2ms (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 2ms (regardless if CRC4 is
enabled) on transmit multiframe boundaries. Used to alert the
host that signaling data needs to be updated.
SEC
SR2.4
1-Second Timer. Set on increments of 1 second based on
RCLK. If CCR2.7 = 1, then this bit will be set every 62.5 ms
instead of once a second.
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 the
LOTC pin high if enabled via TCR2.0.
RCMF
SR2.1
Receive CRC4 Multiframe. Set on CRC4 multiframe
boundaries; will continue to be set every 2ms on an arbitrary
boundary if CRC4 is disabled.
TSLIP
SR2.0
Transmit Elastic Store Slip. Set when the elastic store has
either repeated or deleted a frame of data.
