Configuration and Mode-Select Signals
Table 12 lists and describes the LXT384 Transceiver configuration and mode-select signals. For
multi-function pins, the pin name in blue bold print indicates the signal being discussed.

Codec Enable Select Input.
When the LXT384 Transceiver is in the Hardware mode, CODEN
determines the line encoder/decoder selection when in unipolar
mode. When CODEN is:
Low, it enables an HDB3 encoder/decoder for E1 or a B8ZS
encoder/decoder for T1.
High, it enables an AMI encoder/decoder (transparent mode).
NOTE: In the host processor mode, the encoding/decoding type
is determined by the CODEN bit. (For CODEN bit details,
see Chapter 8.0, “Registers”.)
For other pin functions, see INTL/MOT.

DI
Host Processor Select Input.
When the LXT384 Transceiver is in the host processor mode and
this signal is:
high, the host processor interface is configured for Intel
microcontrollers.
low, the host processor interface is configured for Motorola
microcontrollers.
For other pin functions, see CODEN.
CS / JASEL

J11
DI
Chip Select Input.
In Host Mode, this active Low input is used to access the serial/
parallel interface. For each read or write operation, CS must
transition from High to Low, and remain Low.
For information on the CS signal, see Section 5.2,
“Microprocessor-Standard Bus and Interface Signals”.
CS / JASEL

DI
Jitter Attenuator Select Input.
When the LXT384 Transceiver is in the Hardware mode, JASEL
determines the jitter attenuator (JA) position, as listed in the
following table.
For other pin functions, see CS in Section 5.2, “Microprocessor-
Standard Bus and Interface Signals”.
