Bit 4: Transmit Zero Suppression Encoding Disable (TZSD)
Bit 3: Excessive Zero Insert Enable (EXZI). See Section 8.2.3.
Bit 2: Bipolar Violation Insert Enable (BPVI). See Section 8.2.3.
Bit 1: Transmit Single Error Insert (TSEI). When LINE.TCR:MEIMS = 0, this bit is used to insert errors of the
type(s) specified by EXZI and BPVI in the transmit data stream. A zero-to-one transition causes a single error to be
inserted. For a second error to be inserted, this bit must be set to 0, and then back to 1. Note: If LINE.TCR:MEIMS
is low, and this bit transitions more than once between error insertion opportunities, only one error is inserted. See
Section 8.7.5.
Bit 0: Manual Error Insert Mode Select (MEIMS). This bit specifies the source of the error insertion signal for the
transmit encoder/decoder block. Note: If the TMEI pin or TSEI bit is one, changing the state of this bit may cause
an error to be inserted. See Section 8.7.5.

0 = zero suppression (B3ZS or HDB3) encoding is enabled
1 = zero suppression (B3ZS or HDB3) encoding is disabled, and only AMI encoding is performed
0 = excessive zero event (EXZ) insertion is disabled
1 = excessive zero event insertion is enabled
0 = bipolar violation (BPV) insertion is disabled
1 = bipolar violation insertion is enabled.
0 = Block-level error insertion using the LINE.TCR:TSEI control bit
1 = Port-level or global-level error insertion as specified by PORT.CR1:MEIMS
