Signaling Interface: Pins and Functions for SLIC Interfaces
5.3.2
Debouncing Functions and Interrupt Generation
All signaling inputs are sampled at programmable intervals (Field N in register XR4). If
all the inputs assigned to one channel-pair (1&2 or 3&4) have been stable for two
subsequent samples their values are stored in the signaling registers and the associated
interrupt output (INT12 or INT34) is set high. Refer to the
Programmer’s Reference
Manual
for further details on this function.
5.3.3
Clock Output Signals
Two programmable Chopper Clock Output signals are provided by the PEB 2466:
CHCLK1 (Pin 33) is configured in register XR4.Field T (bits XR4.3 to XR4.0)
CHCLK2 (Pin 16) is configured in register XR5.CHCLK2 (bits XR5.3 and XR5.2)
Both Chopper Clock Output signals are only available if a valid Master Clock signal is
applied to pin MCLK.
CHCLK2 = 16,384 kHz: Requires at least one channel in POWER-UP state.
