Additional two interrupt pins (INT12, INT34) are provided. If one of the input pins for
channel 1 or 2, or one of the bi-directional pins for channel 1 and 2 (if programmed as
inputs) changes, and being stable for the debounce time specified in Register XR4,
INT12 will go from ‘0’ to ‘1’. This interrupt is cleared if the appropriate registers (XR0,
XR1 and XR3) are read via the serial
functionality for channel 3 and 4.
2.6
For special purposes two additional output signals are provided by the SICOFI-2/4 TE.
RGEN (see also register XR4) will provide a programmable ring generator output of 2 to
28 ms. The output of RGEN diveded by four can be used to drive the ring input of a ringin
SLIC. RGEN delivers a square-wave signal (duty cycle 1:1).
CHCLK will provide 3 different frequencies (256 kHz, 512 kHz or 16384 kHz). Both
signals are only available if a valid signal is applied to the DCL-pin.
