Description
TDS
[5] rwc-_-_
TSYNC Direction Select. (only valid when TIOE = 1).
0 = TSYNC is an input
1 = TSYNC is an output
TOES
[4] rwc-_-_
Transmit Output Edge Select.
0 = TDM Port TDAT/TSIG/TSYNC outputs timed using TCLKO positive edge
1 = TDM Port TDAT/TSIG/TSYNC outputs timed using TCLKO negative edge
TIES
[3] rwc-_-_
Transmit Input Edge Select. (only valid when TDS = 1)
0 = TDM Port TSYNC input timed using TCLKO positive edge
1 = TDM Port TSYNC input timed using TCLKO negative edge
TSS
[2:0] rwc-_-_
TCLKO Source Select selects the timing source for TCLKO.
0 = RCLKn pin input signal
1 = internal aclk_n signal (port “n” recovered clock)
2 = internal grclk signal (globally selected recovered clock)
4 = EXTCLK[0] pin input signal
5 = EXTCLK[1] pin input signal
all other values are reserved
PTCR3.

Port Transmit Configuration Register 3. Default: 0x00.00.00.00
PRPTTSL
[31:0] rwc-_-_
PR to PT Time Slot Loop = “1” enables the TDM Port Timeslot Loopback from
RDAT, RSYNC, RSIG to TDAT, TSYNC, TSIG respectively (1 bit for each
timeslot; for T1, bits 31:24 are not used). The transmit timing is not automatically
changed when PRPTLL = 1. Pn.PTCR2.TSS must be programmed so the
incoming RDAT data stream timing is used to time TCLKO and RCLK. PRPTLL =
1 over-rides Pn.PTCR2.TDS forcing TSYNC to be an output. Any number of
timeslots can be in loopback while others Timeslot are not in loopback, but the
receive TDM Port timing and all RXP packet data streams must be frequency
synchronized to work error free. This loopback is only valid if Pn.PTCR1.SFS = 1
(CES).
0 = pass Timeslot data from RXP packets to TDAT/TSYNC/TSIG (normal)
1 = loopback Timeslot data from RDAT/RSYNC/RSIG to TDAT/TSYNC/TSIG
