Sa8 Bit Select. Set to one to source the Sa8 bit from the
TLINK pin; set to zero to not source the Sa8 bit. See Section
22 for timing details.
Sa7 Bit Select. Set to one to source the Sa7 bit from the
TLINK pin; set to zero to not source the Sa7 bit. See Section
22 for timing details.
Sa6 Bit Select. Set to one to source the Sa6 bit from the
TLINK pin; set to zero to not source the Sa6 bit. See Section
22 for timing details.
Sa5 Bit Select. Set to one to source the Sa5 bit from the
TLINK pin; set to zero to not source the Sa5 bit. See Section
22 for timing details.
Sa4 Bit Select. Set to one to source the Sa4 bit from the
TLINK pin; set to zero to not source the Sa4 bit. See Section
22 for timing details.
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)
1 = Loss of Transmit Clock (LOTC)
