5.20 General-Purpose Input/Output
The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.
When configured as an output, you can write to an internal register to control the state driven on the
output pin. When configured as an input, you can detect the state of the input by reading the state of the
internal register. The GPIO can also be used to send interrupts to the CPU.
The GPIO peripheral supports the following:
?
?
?
Up to 26 GPIOs plus 1 general-purpose output (XF) and 4 Special-Purpose Outputs for Use With SAR
The 26 GPIO pins have internal pulldowns (IPDs) which can be individually disabled
The 26 GPIOs can be configured to generate edge detected interrupts to the CPU on either the rising
or falling edge
The device GPIO pin functions are multiplexed with various other signals. For more detailed information
on what signals are multiplexed with the GPIO and how to configure them, see Section 2.5 , Terminal
Functions and Section 3 , Device Configuration of this document.
