GPIO Service Names

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.

0x00090082 BindInterrupt None
0x000A0042 UnbindInterrupt None

GPIO Bitmask

The bitmask used by GetIRGPIO(and likely others) determines which bits in the GPIO registers to access. The output value from GetIRGPIO 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
0-2 (0x7) 0x10147000 0-2
3-4 (0x18) 0x10147010 0-1
5 (0x20) 0x10147014 0
6-17 (0x3FFC0) 0x10147020 0-11
18 (0x40000) 0x10147028 0
