Abstract:
In an example embodiment there is described herein an apparatus, comprising a device having an input and an output, a controllable selecting device having a first input coupled to input of the device and a second input coupled to the output of the device, and a selection control circuit having a test input for receiving a test signal and a power mode input for receiving a power mode signal. The selection control circuit is coupled to the controllable selecting device and operable to control which input the controllable selecting device selects. The selection control circuit is configured to select the first input to isolate the device responsive to the test signal indicating no testing is being performed the power mode signal indicating a low power mode.
