SYNCE:
The SYNCE bit enables the generation of an interrupt when the pattern
detector changes synchronization state. When SYNCE is set to logic 1, the
interrupt is enabled.
BEE:
The BEE bit enables the generation of an interrupt when a bit error is
detected in the receive data. Bit errors are not flagged unless the pattern
detector is synchronized. Loss of synchronization may result in the
generation of a bit error interrupt. When BEE is set to logic 1, the interrupt is
enabled.
XFERE:
The XFERE bit enables the generation of an interrupt when an accumulation
interval is completed and new values are stored in the receive pattern
registers, the bit counter holding registers, and the error counter holding
registers. When XFERE is set to logic 1, the interrupt is enabled.
SYNCV:
The SYNCV bit indicates the synchronization state of the pattern detector.
When SYNCV is a logic 1 the pattern detector is synchronized (the pattern
detector has observed at least 48 consecutive error free bit periods). When
SYNCV is a logic 0, the pattern detector is out of sync (the pattern detector
has detected 10 or more bit errors in a fixed 48-bit window).
