11. In a controller of a control device, a method of changing a state of the control device, the method comprising:
-
while the control device is set in a low-power state, triggering an interrupt responsive to detecting from a motor of the control device a voltage that is greater than a threshold voltage; and setting the control device to a normal state responsive to the interrupt. - View Dependent Claims (12, 13, 14)

15. A game controller, comprising:
-
a rumble motor; a drive module configured to drive the rumble motor; a signal filter configured to receive input from the rumble motor; an amplifier configured to receive input from the signal filter; a comparator configured to receive input from the amplifier; and a controller configured to; selectively connect the rumble motor to the drive module and the signal filter via a switching element responsive to a state of the game controller; send an output signal to the drive module to drive the motor during a normal state; and receive an input signal from the comparator to selectively change the state of the control device responsive to the input signal during a low-power state. - View Dependent Claims (16, 17, 18, 19, 20)
