An example device includes a data port to provide a data channel to a host and a processor coupled to the data port. The processor includes an operational mode and a low-power mode in which the processor is to perform fewer operations than in the operational mode. The processor is to execute instructions in the operational mode and to update the instructions with updated instructions received via the data channel in the operational mode. The device further includes a side channel to receive a signal from the host to trigger the processor to switch from the low-power mode to the operational mode and to initiate update of the instructions with the updated instructions.
A device comprising:
A device comprising:
A non-transitory machine-readable storage medium comprising host instructions that, when executed by a processor of a computer device, trigger output of a signal by the computer device to an accessory device connected to the computer device, wherein the accessory device is connectable to an external device and is to operate in a low-power mode when unconnected to the external device, the signal to trigger the accessory device to exit the low-power mode when unconnected to the external device, and the host instructions further to communicate updated instructions from the computer device to the accessory device after triggering output of the signal.
