General Purpose I/O (GPIO)
22.1
This chapter describes the general-purpose I/O module, including pin descriptions, register settings, and
interrupt capabilities.
22.1.1
The GPIO module supports general-purpose I/O ports.Each port can be configured as an input or as an
output. If a port is configured as an input, it can optionally generate an interrupt on detection of a change.
If a port is configured as an output, it can be individually configured as an open-drain or a fully active
output.
22.1.2
The GPIO unit implements the following features:

Peripheral Bus
All signals are configured as inputs when the device comes out of reset and also when HRESET is
asserted.
Open-drain capability on all ports
All ports can optionally generate an interrupt upon changing their state.
