Output Data Mode
0 = pulses at TPOSO and TNEGO are one full TCLKO
period wide
1 = pulses at TPOSO and TNEGO are 1/2 TCLKO period
wide
Automatic E-Bit Enable
0 = E–bits not automatically set in the transmit direction
1 = E–bits automatically set in the transmit direction
Function of RLOS/LOTC Pin
0 = Receive Loss of Sync (RLOS)
