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 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. | |||
