Abstract

PURPOSE:To prevent consumption of reactive power by providing a microcomputer having a sleep function containing two interruption ports to each of plural secondary units and holding a sleep mode until the next interruption processing occurs after the interruption processing is through to 1st and 2nd interruption ports. CONSTITUTION:A microcomputer CPU 1 set in a secondary unit 6 has a sleep mode and a normal action mode by means of software. When an interruption signal is inputted to a terminal iR02 in a sleep mode, the CPU 1 sets a timer for an internal interruption. Then the CPU 1 masks the terminal iR02 and inhibits the input of the next interruption signal before the masking of the terminal iR20 is released. Furthermore the CPU 1 transits again in a sleep mode after setting the incoming start data at a transmission buffer and waits for input of both terminals iR01 and iR03. When the periodical interruption request signals are inputted to the terminal iR01 from a main unit, the CPU 1 wakes up and transits in a normal action mode.
