Shared I/O pins (PL_GPIOs)
The 98 PL_GPIO and 4 PL_CLK pins have the following characteristics:
The PL_GPIOs can be configured in different modes. This allows SPEAr320 to be tailored
for use in various applications like:

Configuration modes
This section describes the main operating modes created by using a selection of the
embedded IPs.
The following modes can be selected by programming some control registers present in the
reconfigurable array subsystem.
