SLIC off-hook threshold register (ITH)
Addr=2Eh; reset value=00h
Table 40.
●
●
The step is equal to 1 mA.
●
●
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 12.5 kohm resistor in kit with STLC3080.
PCM shift register (PCMSH)
Addr=50h; reset value=00h
Table 41.
●
●
PCM command register (PCMCOM)
Addr=51h; reset value=00h
Table 42.
TPA/B = These two bits are used to enable the DX outputs of the port A and/or B. According
to the combination of these two bits the enabled port will be as follows:

D3..0 = 0: Programmed value is 16 mA
D3..0 = 1: Programmed value is 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)
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.
