Overall transmit gain depends on combination of TXG and GTXn registers.
Receive amplifier gain register (RXG)
Addr=2Ch; reset value=00h
Table 38.

Overall receive gain depends on the receive amplifier gain (R3..0) setting in RXG reg. and
digital gain (GRXn reg. setting).
SLIC line current limit reg (ILIM)
Addr=2Dh; reset value=00h
Table 39.

The step is 1.6 mA.
This register allows to program a line current limitation from 2 to 53 mA with a step equal to
1.6 mA. These values can be obtained using an external 15 kohm resistor in kit with
STLC3080.
