Hardware Reference Manual
5.3.2
All signaling inputs are sampled at programmable intervals (Field N in register XR4). If
all the inputs assigned to one channel-pair (1&2) have been stable for two subsequent
samples their values are stored in the signaling registers and the associated interrupt
output (INT12) is set high. The debouncing functions and interrupt generation require a
1536 kHz signal on Pin 22 (DCL). If, for power savings reasons, DCL is temporarily
disabled, a signaling change interrupt can be generated by external hardware. Refer to
the Programmer’s Reference Manual for further details on this function.
5.3.3
Two programmable Clock Output signals are provided by the PSB 2132:
• RGEN (Pin 33) divided by two can drive the ring input of a ringing SLIC. It is configured
• CHCLK (Pin 16) is configured in register XR5.CHCLK.
• CHCLK = 16,384 kHz: Requires at least one channel in POWER-UP state.

The Serial Microcontroller Interface is used to access the SICOFI
registers and the Coefficient RAM (CRAM). The Serial Microcontroller Interface consists
of four pins: two data pins (DIN, DOUT), one clock pin (DCLK) and one pin for chip select
(CS#). If DIN and DOUT are strapped together, only three microcontroller I/O pins are
required to build this interface.
