Rapid GPIO (RGPIO)
5.1.2
The major features of the RGPIO module providing 16 bits of high-speed general-purpose input/output
are:
5-4
•
•
Small memory-mapped device connected to the processor’s local bus
— All memory references complete in a single cycle to provide zero wait-state responses
— Located in processor’s high-speed clock domain
Simple programming model
— Four 16-bit registers, mapped as three program-visible locations
– Register for pin enables
– Register for controlling the pin data direction
– Register for storing output pin data
– Register for reading current pin state
