This bit selects the EXZ definition standard.
0: ANSI. (default)
1: FCC.
This bit controls whether to insert a bipolar violation (BPV) to the transmit path.
Writing ‘1’ to this bit will insert a BPV on the next available mark in the data stream to be transmitted.
This bit is cleared once the BPV insertion is completed.
This bit controls whether to insert a single bit error to the generated PRBS/ARB pattern.
A transition from ‘0’ to ‘1’ on this bit will insert a single bit error to the generated PRBS/ARB pattern.
This bit is cleared once the single bit error insertion is completed.
000: Disable. (default)
001: LBPV.
010: LEXZ.
011: LBPV + LEXZ.
100: SBPV.
101: SEXZ.
110: SBPV + SEXZ.
111: PRBS/ARB error.
This bit determines whether the ERRCH & ERRCL registers are updated automatically or manually.
0: Manually by setting the CNT_STOP bit (b0, ERR,...). (default)
1: Every-one second automatically.
This bit is valid only when the CNT_MD bit (b1, ERR,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit updates the ERRCH & ERRCL registers.
This bit must be cleared before the next round.
These bits select the period. When the amplitude of the data is less than a certain voltage for the period, TLOS is declared. The
voltage is determined by the TALOS bits (b3~2, LOS,...).
00: 16-pulse.
01: 32-pulse. (default)
1X: 64-pulse.
