Abstract

PURPOSE: To avoid misoutput at package replacement, by supplying the reset signal to all the packages after detection of mounting of package through the condition of the short circuit of various types of output packages.
CONSTITUTION: Depending on the ON or OFF signal from the short circuit sections 12aW12n provided with various types of output packages 10aW10n, the mounting of the packages 10aW10n is detected by the signal detection sections 13aW 13n for plug mounting. Further, this detection signal (broken lines in Figure) is fed to the reset signal introduction section 2 of the microcomputer 1 through the input and output control package 8 and extension package 7 with the bus signal lines 5aW5c. Further, the detection signal fed feeds the reset signal (solid lines in Figure) to all the packages 10aW10n, 7 and 8.
