Data Sheet
7.8.2
Fast external interrupts may also have interrupt sources selected from other peripherals.
This function is very advantageous in Slow Down mode or in Sleep mode, if for example
the SSC interface shall be used to wake-up the system. The register EXISEL is used to
switch the receive inputs of the serial interfaces to the fast external interrupts, in order to
detect incomming messages in case of disabled serial interface modules.
EXISEL register is defined as follows:
