Input sensing is synchronous or asynchronous depending on the enabled clock for the ports, and the configuration is 
shown in 

When a pin is configured with inverted I/O, the pin value is inverted before the input sensing.

Most port pins have alternate pin functions in addition to being a general purpose I/O pin. When an alternate function is 
enabled, it might override the normal port pin function or pin value. This happens when other peripherals that require pins 
are enabled or configured to use pins. If and how a peripheral will override and use pins is described in the section for 
that peripheral. 

 shows which modules on peripherals that enable alternate 

functions on a pin, and which alternate functions that are available on a pin.
