ABSTRACT:
An electronic device is reset using a reset line internal to the electronic device. The electronic device includes internal logic circuitry which performs logic operations. An internal logic power signal input to the electronic device is connected to an internal logic power signal line. The internal logic power signal line is used to deliver an internal logic power signal to the internal logic circuitry. The electronic device also includes a plurality of outputs. A plurality of output drivers buffer output signals generated by the internal logic circuitry. The output drivers place the output signals on the plurality of outputs. The electronic device additionally includes an output power signal input connected to an output power signal line. The output power signal line is used to deliver an output power signal from the output power signal input to the output drivers. A reset line, connected to the output power signal line and to the internal logic circuitry, is used to reset the internal logic circuitry. A reset cycle is begun by placing the internal logic power signal on the internal logic power signal line while placing a ground signal on the output power signal line. The reset cycle is completed by placing the output power signal on the output power signal line.
