The General Purpose Input/Output Controller (GPIO) controls the I/O pins of the microcontroller.
Each GPIO pin may be used as a general-purpose I/O or be assigned to a function of an embed-
ded peripheral.
The GPIO is configured using the Peripheral Bus (PB). Some registers can also be configured
using the low latency CPU Local Bus. See
Figure 18-1. GPIO Block Diagram
Each GPIO line features:
– Configurable pin-change, rising-edge, or falling-edge interrupt
– Configurable peripheral event generator
– Glitch filter providing rejection of pulses shorter than one clock cycle
– Input visibility and output control
– Multiplexing of peripheral functions on I/O pins
– Programmable internal pull-up resistor
– Optional locking of configuration to avoid accidental reconfiguration
