illustrated.
Figure 64. GPIO Port Pin Block Diagram
Many of the GPIO port pins can be used as both general-purpose I/O and to provide access
to on-chip peripheral functions such as the timers and serial communication devices. The
Port A-H 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
