| 16 | * pin configurations are represented by 32-bit integers: | |
| 17 | * | |
| 18 | * bit 0.. 8 - Pin Number (512 Pins Maximum) | |
| 19 | * bit 9..10 - Alternate Function Selection | |
| 20 | * bit 11..12 - Pull up/down state | |
| 21 | * bit 13 - Sleep mode behaviour | |
| dacdc96c RV |
22 | * bit 14 - Direction |
| 23 | * bit 15 - Value (if output) | |
| 24 | * bit 16..18 - SLPM pull up/down state | |
| 25 | * bit 19..20 - SLPM direction | |
| 26 | * bit 21..22 - SLPM Value (if output) | |

| 28 | * to facilitate the definition, the following macros are provided | |
| 29 | * | |
| 30 | * PIN_CFG_DEFAULT - default config (0): | |
| 31 | * pull up/down = disabled | |
| 7e3f7e59 | 32 | * sleep mode = input/wakeup |
| dacdc96c RV |
33 | * direction = input |
| 34 | * value = low | |
| 35 | * SLPM direction = same as normal | |
| 36 | * SLPM pull = same as normal | |
| 37 | * SLPM value = same as normal | |
| 378be066 RV |

| 39 | * PIN_CFG - default config with alternate function | |
| 40 | * PIN_CFG_PULL - default config with alternate function and pull up/down | |
