13
  The Freescale PORT/GPIO modules are two adjacent modules providing GPIO

14
  functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of

15
  each, and each PORT module has its own interrupt.

16


17
  Note: Each GPIO port should have an alias correctly numbered in "aliases"

18
  node.
