GPIO Service Names[edit]
| Service name | Permitted GPIO bitmasks |
|---|---|
| gpio:CDC | 0x48 |
| gpio:MCU | 0x48020 |
| gpio:HID | 0x4301 |
| gpio:NWM | 0x40020 |
| gpio:IR | 0xEC0 |
| gpio:NFC | 0x13000 |
| gpio:QTM | 0x20000 |
For the mapping between GPIO bitmasks and IRQs see: GPIO:BindInterrupt#Supported_values.
The commands for these services are identical.
The input bitmask for each command is masked with the above permission bitmask, if the result is non-zero an error is occurred.
GPIO Services[edit]
| Command Header | Description | Uses GPIO Regs |

| 0x00090082 | BindInterrupt | None |
| 0x000A0042 | UnbindInterrupt | None |
GPIO Bitmask[edit]
The bitmask used by the service commands determines which bits in the GPIO registers to access. The output value from GetGPIOData uses the same format as the bitmask: the values of bits in the output field are set to the value of GPIO data when those bits are set in the input bitmask.
| Bits in the bitmask | Register | Bits from register | Handled with GPIO:SetGPIOData |
|---|---|---|---|
| 0-2 (0x7) | 0x10147000 | 0-2 | No |
| 3-4 (0x18) | 0x10147010 | 0-1 | Yes |
| 5 (0x20) | 0x10147014 | 0 | Yes |
| 6-17 (0x3FFC0) | 0x10147020 | 0-11 | Yes |
| 18 (0x40000) | 0x10147028 | 0 | Yes |
