Read returns zero.
Reference Clock LOS Alarm.
Loss of signal on the reference clock input, based on a coarse deviation in frequency.
Loss of Signal Alarm.
Loss of signal on the transmitter input. (TD)
Loss of Lock Alarm.
The transmitter PLL has lost lock with the transmitter input signal. (TD)
Transmitter FIFO Error Alarm.
The transmitter FIFO has overflowed or underflowed. If FIFOAutoReset is active
(Reg156[1] = 1), this bit is automatically cleared when a FIFO over/under flow has
occurred.
Test Pattern Generator/Checker Alarm.
The transmitter test pattern checker has reached the predetermined error count set in
Register 175.
Test Pattern Checker Loss-of-Sync Alarm.
The receiver test pattern checker has lost sync with the pattern. When the test pattern
checker is disabled, this bit is automatically set to 0. When the test pattern checker is
enabled, an “I” in this location means the test pattern checker has lost synchronization
between the expected pattern and the received pattern.
Signal Quality Monitor Alarm.
The internal signal quality monitor value has met the predetermined threshold value.
