In order to use this module, other parts of the system must be configured correctly, as described
below.
The IISC pins may be multiplexed with I/O Controller lines. The user must first program the I/O
Controller to assign the desired IISC pins to their peripheral function. If the IISC I/O lines are not
used by the application, they can be used for other purposes by the I/O Controller. It is required
to enable only the IISC inputs and outputs actually in use.
If the CPU enters a sleep mode that disables clocks used by the IISC, the IISC will stop function-
ing and resume operation after the system wakes up from sleep mode.
