Bit 0: Transmit FEAC Idle Interrupt Enable (TFIIE). This bit enables an interrupt if the TFIL bit in the
register is set.
Bit 1: Receive FEAC Codeword Detected Interrupt Enable (RFCDIE). This bit enables an interrupt if the RFCDL
Bit 2: Receive FEAC Idle Interrupt Enable (RFIIE). This bit enables an interrupt if the RFIL bit in the
register is set.
Bit 3: Receive FEAC FIFO Not-Empty Interrupt Enable (RFFNIE). This bit enables an interrupt if the RFFNL bit
in the
Bit 4: Receive FEAC FIFO Overflow Interrupt Enable (RFFOIE). This bit enables an interrupt if the RFFOL bit in
