Single Bit Defect Insertion Register (Read/Write)
Value after reset: 00
IERR
After setting the corresponding bit, the selected defect is inserted into the transmit data
stream at the next possible position. After defect insertion is completed, the bit is reset
automatically.

Transmit Code
00 = NRZ (optical interface)
01 = CMI (1T2B+B8ZS), (optical interface)
10 = AMI coding with Zero Code Suppression (ZCS, B7-stuffing).
11 = B8ZS Code (ternary or digital dual-rail interface).
After changing XC(1:0), a transmitter software reset is required
(CMDR.XRES = 1).
Receive Code

H
H
after defect insertion.
Disabling of the ZCS is done by activating the clear channel
mode by register CCB(3:1). (ternary or digital interface)
