Input sensing
Port Interrupt
Alternate Port Functions
Input sensing is synchronous or asynchronous depending on the enabled clock for the ports,
and the configuration is shown in
Figure 15-7. Input sensing system overview
When a pin is configured with inverted I/O, the pin value is inverted before the input sensing.
Each port has two interrupts with separate priority and interrupt vector. All pins on the port can
be individually selected as source for each of the interrupts. The interrupts are then triggered
according to the input sense configuration for each pin configured as source for the interrupt.
In addition to the input/output functions on all port pins, most pins have alternate functions. This
means that other modules or peripherals connected to the port can use the port pins for their
functions, such as communication or pulse-width modulation.
