TSR.7
Set when the receiver detects 16 consecutive 0s; cleared when
IMR.7 is cleared.
JALT
TSR.6
Set when the jitter attenuator FIFO reaches to within 4 bits of its
limit; cleared when IMR.6 is cleared.
DFMO
TSR.5
Set when SR.5 changes state; cleared when IMR.5 is cleared.
B8ZSD
TSR.4
Set when the receiver detects B8ZS codewords; cleared when
IMR.4 is cleared.
QRSS
TSR.3
Set when SR.3 changes state; cleared when IMR.3 is cleared.
AIS
TSR.2
Set when SR.2 changes state; cleared when IMR.2 is cleared.
NLOOP
TSR.1
Set when SR.1 changes state; cleared when IMR.1 is cleared.
RCL
