BIT DESCRIPTION
R/W AUXP Enable:
AUXP is an unframed 1010 pattern.
When this bit is set to zero:
AUXP generation is disabled.
When this bit is set to one:
AUXP generation is enabled.
R/W Loss of Frame Declaration Enable:
This READ/WRITE bit-field permits the framer to declare Red
Alarm in case of Loss of Frame Alignment (LOF).
When receiver module of the framer detects Loss of Frame
Alignment in the incoming data stream, it will generate a Red
Alarm. The framer will also generate an RxLOFs interrupt to
notify the microprocessor that an LOF condition is occurred. A
Yellow Alarm is then returned to the remote transmitter to report
that the local receiver detects LOF.
When this bit is set to zero:
Red Alarm declaration is disabled.
When this bit is set to one:
Red Alarm declaration is enabled.
