Bit 0: Synchronization Status Interrupt Enable (SYNCIE). This bit enables an interrupt if the SYNCL bit in the
BSRL
Bit 1: BERT Error-Counter Overflow Interrupt Enable (BECOIE). This bit enables an interrupt if the BECOL bit
in the
Bit 2: BERT Bit-Counter Overflow Interrupt Enable (BBCOIE). This bit enables an interrupt if the BBCOL bit in
the
Bit 3: Bit Error-Detected Interrupt Enable (BEDIE). This bit enables an interrupt if the BEDL bit in the
register is set.
