Bit 3: Automatic Error-Counters Update Defeat (AECU). When this bit is logic 0, the device automatically

updates the DS3/E3 performance error counters on an internally created 1-second boundary based on the RCLK

or TCLK signal, depending on the OSTCS control bit. The host processor is notified of the update through the

setting of the OST status bit in the MSRL register. In this mode, the host processor has a full 1-second period to

retrieve the error count information before it is overwritten with the next update. When this bit is set high, the device

disables the automatic 1-second update and enables a manual update mode. In the manual update mode, the

device relies on either the RECU hardware input signal or the MECU control bit to update the error counters. The

RECU hardware input signal and MECU control bit are logically ORed and therefore a 0-to-1 transition on either

initiates an error counter update. After either the RECU signal or MECU bit has toggled, the host processor must

wait at least 100ns before reading the error counters to allow the device time to complete the update.

0 = enable the automatic update mode and disable the manual update mode

1 = disable the automatic update mode and enable the manual update mode

Bit 4: Manual Error-Counter Update (MECU). A 0-to-1 transition on this bit causes the device to update the

performance error counters. This bit is ignored if the AECU control bit is logic 0. This bit must be cleared and set

again for a subsequent update. This bit is logically ORed with the RECU input pin.

Bit 5: DS3/E3 POS/NEG Binary Mode Select (BIN). Selects the mode of the LIU interface signals.

0 = dual-rail mode (data on TPOS/TNEG and RPOS/RNEG)

1 = binary NRZ mode (data on TNRZ and RNRZ with line-code violation pulses on RLCV)

Bit 6: Zero Code Suppression Disable (ZCSD). When BIN = 1, zero code suppression is automatically disabled

and ZCSD has no effect.

0 = enable the B3ZS/HDB3 encoder and decoder; coding is AMI with zero substitution

1 = disable the B3ZS/HDB3 encoder and decoder; coding is AMI without zero substitution

Bit 7: Loss-of-Transmit Clock Mux Control (LOTCMC). The device can detect if the TICLK fails to transition. If

this bit is logic 0, the device takes no action (other than setting the LOTC status bit) when the TICLK fails to

transition. If this bit is logic 1, when TICLK fails to transition the device automatically switches the transmitter to the

input receive clock (RCLK) and transmits AIS.

0 = do not switch the transmitter to RCLK if TICLK fails to transition

1 = automatically switch the transmitter to RCLK and transmit AIS if TICLK fails to transition
