| 12 | description: | |
| 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. |
