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) | |

27 | * |
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 |
38 | * |
39 | * PIN_CFG - default config with alternate function | |
40 | * PIN_CFG_PULL - default config with alternate function and pull up/down | |
