General Purpose I/O (GPIO)
21.2
The following section provides information about GPIO signals.
21.2.1
Table 21-1
21.3
The GPIO has programmable registers that occupy 24 bytes of 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. All addresses used in this
chapter are offsets from the address held in IMMRBAR as defined in

I/O
I/O General purpose I/O. Each signal can be set individually to act as input or output, according to application
needs.
Meaning
Timing Assertion/Negation—Inputs can be asserted completely asynchronously.
