The commands for these services are identical.
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 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.
The bitmask used by the service commands determines which bits in the GPIO registers to access. The output value from [[GPIO:GetGPIOData|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.
