Register XR4 provides two optional functions: debouncing of signaling input changes,
and the configuration of the programmable output pin CHCLK1.
Signaling Debounce Interval N
To restrict the rate of changes on signaling input pins transferred, deglitching of the
status information from the SLIC may be applied. New status information will be read into
registers XR0, XR1, XR2 and XR3, and an interrupt on pin INT12 (INT34) will be
generated, after it has been stable for N milliseconds. N is programmable in the range of
2 to 30 ms in steps of 2 ms, with N = 0 the debouncing is disabled.
