Codec Enable Select Input.
When the LXT385 ransceiver is in the Hardware mode, CODEN
determines the line encoder/decoder selection when in unipolar
mode. When CODEN is:

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

Jitter Attenuator Select Input.
When the LXT385 ransceiver is in the Hardware mode, JASEL
determines the jitter attenuator (JA) position, as listed in the
following table.
