SLIC Line Current Limit reg (ILIM)

Addr=2Dh; Reset Value=00h

D4..0 = 0: Programmed value is 53

D4..0 = 1: Programmed value is 2

The step is 1.6 mA

This register allows to program a line current limitation from 2 to 53mA with a step equal to 1.6mA. These values

can be obtained using an external 15KOhm resistor in kit with STLC3080.

SLIC Off-Hook threshold register (ITH)

Addr=2Eh; Reset Value=00h

D3..0 = 0: Programmed value is 16 mA

D3..0 = 1: Programmed value is 1 mA

The step is equal to 1 mA.

En = 1 The DC SLIC programmability block is enabled (ITH and ILIM)

En = 0 The DC SLIC programmability block is disabled (ITH and ILIM)

This register allows to program a threshold value from 1 to 16 mA with a step equal to 1mA. These values can

be obtained using an external 12.5KOhm resistor in kit with STLC3080.

PCM Shift Register (PCMSH)

Addr=50h; Reset Value=00h

XS2..0:Effective start of the TX frame is the programmed values of clock pulses (0 to 7) after the FS rising edge.

RS2..0:Effective start of the RX frame is the programmed values of clock pulses (0 to 7) after the FS rising edge.

PCM Command register (PCMCOM)

Addr=51h; Reset Value=00h
