NOTE:
The RAIS-CI bit is qualified with the RBL status bit (SR1A.3 and SR1B.3). Hence the RAIS-CI status
bit will not be set unless the RBL status bit is set.
If the RBL bit is set and the RAIS-CI bit has
transitioned from a 1 to a 0 (i.e., it has cleared), it is recommended that the software wait at lest 1.5
seconds and then read the RAIS-CI bit again to make sure that the alarm has indeed cleared.

NAME AND DESCRIPTION
LUP
SR1A.7
Loop Up Code Detected. Set when the loop up code as
defined in the RUPCD register is being received. See Section
12 for details.
LDN
SR1A.6
Loop Down Code Detected. Set when the loop down code as
defined in the RDNCD register is being received. See Section
12 for details.
LOTC
SR1A.5
Loss of Transmit Clock. Set when the TCLKA pin has not
transitioned for one channel time (or 5.2
s). Will force the
RLOSA/LOTCA pin high if enabled via CCR1A.6. Also will
force transmit side formatter to switch to MCLK if so enabled
via TCR1A.7.
LSPARE
SR1A.4
Spare Code Detected. Set when the spare code as defined in
the RSPARE register is being received. See Section 12 for
details.
RBL
SR1A.3
Receive Blue Alarm. Set when an unframed all 1’s code is
received at RPOSIA and RNEGIA.
RYEL
SR1A.2
Receive Yellow Alarm. Set when a yellow alarm is received
at RPOSIA and RNEGIA.
FRCL
SR1A.1
Framer Receive Carrier Loss. Set when a red alarm is
received at RPOSIA and RNEGIA.
RLOS
SR1A.0
Receive Loss of Sync. Set when the device is not
synchronized to the receive T1 stream.
