General Purpose I/O (GPIO)
21.1
This chapter describes the general-purpose I/O module, including pin descriptions, register settings, and
interrupt capabilities.
21.1.1
The GPIO module supports 32 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.
21.1.2
The GPIO unit implements the following features:

32 input/output ports
Some ports have dedicated processor signals. Others are multiplexed together with other functional
signals. See
All signals are configured as inputs when the device comes out of reset and also when HRESET is
asserted.
