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 1 second based on
RCLK.
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 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
μ
s (3
μ
s ±1
μ
s).
