3. All receive side signals will take on timing synchronous with TCLK instead of RCLKI.
Please note that it is not acceptable to have RCLK tied to TCLK during this loopback because this
will cause an unstable condition.

Transmit Frame Mode Select.
0 = D4 framing mode
1 = ESF framing mode
Transmit B8ZS Enable.
0 = B8ZS disabled
1 = B8ZS enabled
Transmit SLC–96 / Fs–Bit Insertion Enable.
Only set this bit to a one in D4 framing
applications. Must be set to one to source the Fs pattern from the TFDL register. See
Section 15.5 for details.
0 = SLC–96/Fs–bit insertion disabled
1 = SLC–96/Fs–bit insertion enabled
Transmit FDL Zero Stuffer Enable.
Set this bit to zero if using the internal
HDLC/BOC controller instead of the legacy support for the FDL. See Section 15 for
details.
0 = zero stuffer disabled
1 = zero stuffer enabled
Receive Frame Mode Select.
0 = D4 framing mode
1 = ESF framing mode
Receive B8ZS Enable.
0 = B8ZS disabled
1 = B8ZS enabled
Receive SLC–96 Enable.
Only set this bit to a one in D4/SLC–96 framing
applications. See Section 15.5 for details.
0 = SLC–96 disabled
1 = SLC–96 enabled
Receive FDL Zero Destuffer Enable.
Set this bit to zero if using the internal
HDLC/BOC controller instead of the legacy support for the FDL. See Section 15.4 for
details.
0 = zero destuffer disabled

Receive Elastic Store Minimum Delay Mode.
See Section 14.4 for details.
0 = elastic stores operate at full two frame depth
1 = elastic stores operate at 32–bit depth
Transmit Clock Source Select.
This function allows the user to internally select
RCLK as the clock source for the transmit side formatter.
0 = Source of transmit clock determined by TCR1.7 (LOTCMC)
1 = Force transmitter to internally switch to RCLK as source of transmit clock. Signal
at TCLK pin is ignored
Function of the RLOS/LOTC Output.
