for General-Purpose Input/Output (GPIO) operations. Each port consists Control and Data
Registers. The GPIO Control Registers are used to determine data direction, open-drain,
output drive current, programmable pull-ups, Stop Mode Recovery functionality, and
alternate pin functions. Each port pin is individually programmable. Ports A and C support
5 V-tolerant inputs.

ability to accommodate alternate functions, variable port current drive strength, and pro-
grammable pull-up.
Many of the GPIO port pins are used as both general-purpose I/O and to provide access to
on-chip peripheral functions such as timers and serial communication devices. The
Port A–C Alternate Function sub-registers 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–C Data Direction
registers to the alternate function assigned to this pin.
