External Signal Description
45.1.3 Modes of Operation
The RGPIO module does not support any special modes of operation. As a memory-
mapped device located on the processor's high-speed local bus, it responds based strictly
on memory address and does not consider the operating mode (supervisor, user) of its
references.

• Register for pin enables
• Register for controlling the pin data direction
• Register for storing output pin data
• Register for reading current pin state
• The two data registers (read, write) are mapped to a single program-visible
• Support for any access size (byte, word, or longword)
