Figure 7 displays a simplified block diagram of a GPIO port pin. In this figure, the ability
to accommodate alternate functions and variable port current drive strength is not dis-
played.
Many of the GPIO port pins can be used for general-purpose I/O and access to on-chip
peripheral functions such as the timers and serial communication devices. The Port A–D
Alternate Function subregisters configure these pins for either General-Purpose I/O or
alternate function operation. When a pin is configured for alternate function, control of the
port pin direction (input/output) is passed from the Port A–D Data Direction registers to
the alternate function assigned to this pin.
possible with each port pin. For those pins with more one alternate function, the alternate
function is defined through Alternate Function Sets subregisters AFS1 and AFS2.
The crystal oscillator functionality is not controlled by the GPIO block. When the crystal
oscillator is enabled in the oscillator control block, the GPIO functionality of PA0 and PA1
is overridden. In that case, those pins function as input and output for the crystal oscillator.
