Figure 6-1 Block diagram of GPIO demonstration
Block Diagram of GPIO Interface
The HPS provides three general-purpose I/O (GPIO) interface modules.
Figure 6-2
shows the block
diagram of GPIO Interface. GPIO[28..0] is controlled by the GPIO0 controller and GPIO[57..29] is
controlled by the GPIO1 controller. GPIO[70..58] and input-only GPI[13..0] are controlled by the
GPIO2 controller.

GPIO Register Block
The behavior of I/O pin is controlled by the registers in the register block. There are three 32-bit
