Table 13-1.
In order to use this module, other parts of the system must be configured correctly, as described
below.
The external interrupt pins (EXTINTn and NMI) are multiplexed with I/O lines. To generate an
external interrupt from an external source the source pin must be configured as an input pins by
the I/O Controller. It is also possible to trigger the interrupt by driving these pins from registers in
the I/O Controller, or another peripheral output connected to the same pin.
