Bits 0 to 5: Transmit FEAC Codeword A Data (TFCA[5:0]). The FEAC codeword is of the form
…0xxxxxx011111111… where the rightmost bit is transmitted first. TFCA[5:0] are the middle six bits of the second
byte of the FEAC codeword (i.e., the six “x” bits). The transmit FEAC controller can generate two different
codewords. These six bits specify what is to be transmitted for codeword A. TFCA0 is the LSB and is transmitted
first; TFCA5 is the MSB and is transmitted last. The TFS[1:0] control bits determine if this codeword is to be
transmitted. These bits should only be changed when the transmit FEAC controller is in the idle state (TFS[1:0] =
00).

Bits 0 to 5: Receive FEAC FIFO Data (RFF[5:0]). Data from the receive FEAC FIFO can be read from these bits.
The FEAC codeword is of the form …0xxxxxx011111111… where the right-most bit is received first. These six bits
are the debounced and integrated middle six bits of the second byte of the FEAC codeword (i.e., the six “x” bits).
RFF0 is the LSB and is received first; RFF5 is the MSB and is received last.
