Bit 2: Receive FEAC FIFO Overflow Interrupt Enable (RFFOIE) – This bit enables an interrupt if the RFFOL bit
is set and the bit in GL.ISRIE.PSRIE[4:1] that corresponds to this port is set.
Bit 1: Receive FEAC Codeword Detect Interrupt Enable (RFCDIE) – This bit enables an interrupt if the RFCDL
bit is set and the bit in GL.ISRIE.PSRIE[4:1] that corresponds to this port is set.
Bit 0: Receive FEAC Idle Interrupt Enable (RFIIE) – This bit enables an interrupt if the RFIL bit is set and the bit
in GL.ISRIE.PSRIE[4:1] that corresponds to this port is set.

Bit 7: Receive FEAC FIFO Data Invalid (RFFI) – When 0, the Receive FIFO data (RFF[5:0]) is valid. When 1, the
Receive FIFO data is invalid (Receive FIFO is empty).
Bits 5 to 0: Receive FEAC FIFO Data (RFF[5:0]) – These six bits are the FEAC code data stored in the Receive
FIFO. RFF[5] is the LSB (last bit received) of the FEAC code (C[6]), and RFF[0] is the MSB (first bit received) of the
FEAC code (C[1]). The Receive FEAC FIFO data (RFF[5:0]) is updated when it is read (lower byte read).
0 = interrupt disabled
1 = interrupt enabled
0 = interrupt disabled
1 = interrupt enabled
0 = interrupt disabled
1 = interrupt enabled
