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
μ
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 one 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
μ
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
μ
s). Will force the LOTC pin high if enabled via
TCR2.0.
RCMF
SR2.1
Receive CRC4 Multiframe
. Set on CRC4 multiframe boundaries; will con-
tinue to be set every 2 ms on an arbitrary boundary if CRC4 is disabled.
TSLIP
SR2.0
Transmit Elastic Store Slip.
Set when the elastic store has either re-
peated or deleted a frame of data.
