One method to accomplish this would be to tie RCLK to TCLK and RFSYNC to TSYNC. There are no
restrictions on which channels can be looped back or on how many channels can be looped back.

CH1 - 32
TIR1.0 - 4.7
Transmit Idle Code Insertion Control Bits.
0 = do not insert the Idle Code in the TIDR into this channel
1 = insert the Idle Code in the TIDR into this channel
NOTE:
If CCR3.5 = 1, then a zero in the TIRs implies that channel data is to be sourced from TSER and a one
implies that channel data is to be sourced from the output of the receive side framer (i.e., Per–Channel
Loopback; see Figure 3-1).

11.1.2 Per–Channel Code Insertion
The second method involves using the Transmit Channel Control Registers (TCC1/2/3/4) to determine
which of the 32 E1 channels should be overwritten with the code placed in the Transmit Channel
Registers (TC1 to TC32). This method is more flexible than the first in that it allows a different 8–bit
code to be placed into each of the 32 E1 channels.
