General Purpose I/O (GPIO)
22.2
The following section provides information about GPIO signals.
22.2.1
Table 22-1
22.3
The GPIO has programmable registers that occupy memory-mapped space. Note that reading undefined
portions of the memory map returns all zeros and writing has no effect.
All GPIO registers are 32 bits wide and are located on 32-bit address boundaries.
