Abstract
A power saving arrangement for a microcomputer having a first clock signal operating at a predetermined frequency employs a reduced clock frequency to peripheral circuitry to limit power consumption during a disable or halt mode. A control circuit disables a clock signal provided to the microcomputer, while a clock divider divides the predetermined frequency to generate a reduced frequency signal upon which the peripheral circuitry may operate. After receiving an external wake-up signal, the peripheral circuitry interrupts the microcomputer in order to revert the microcomputer back to normal operation.
