of the loopback point continue to operate normally. For example line AIS may

be inserted in the transmit stream upstream of the loopback point using the

TSOP Control register.

SDLE:

The SDLE bit enables the serial diagnostic loopback. When SDLE is a logic

one, the transmit serial stream is connected to the receive stream. The SDLE

and the LLE bits should not be set high simultaneously.

LLE:

The LLE bit enables the S/UNI-PLUS line loopback. When LLE is a logic one,

RXD+ and RXD- are connected internally to TXD+ and TXD- respectively.

The SDLE and the LLE bits should not be set high simultaneously.

RXDINV:

The RXDINV bits select the polarity of the RXD+/- signals. The default

configuration selects RXD+ (RXD-) to be high (low) when the receive stream

contains a logic one. When RXDINV is a logic one, RXD+/- is inverted;

RXD+(RXD-) is low (high) when the receive stream contains a logic one.

RCAINV:

The RCAINV bits select the active polarity of the RCA signal. The default

configuration selects RCA to be active high, indicating that a received cell is

available when high. When RCAINV is a logic one, the RCA signal becomes

active low.

TCAINV:

The TCAINV bits select the active polarity of the TCA signal. The default

configuration selects TCA to be active high, indicating that a cell is available

in the transmit FIFO when high. When TCAINV is a logic one, the TCA signal

becomes active low.
