ability to accommodate alternate functions and variable port current drive strength.
Many GPIO port pins are used for GPIO and to access the on-chip peripheral functions
like the timers and serial-communication devices. The Port A–E Alternate Function
subregisters configure these pins for either GPIO or alternate function operation. When a
pin is configured for alternate function, control of port-pin direction (input/output) is
passed from Port A–E Data Direction registers to the alternate functions assigned to this
pin.
functions possible with each port pin for every package. The alternate function associated
at a pin is defined through alternate function sets subregisters AFS1 and AFS2.
The crystal oscillator and the 32 kHz secondary oscillator functionalities are not
controlled by the GPIO block. When the crystal oscillator or the 32 kHz secondary
oscillator is enabled in the oscillator control block, the GPIO functionality of PA0 and
PA1, or PA2 and PA3, is overridden. In such a case, those pins function as input and
output for the crystal oscillator.
