Abstract
In an aspect of the present invention, a microcomputer includes a CPU core section, and a plurality of external input terminals. A testing section selects a selection external input terminal from the plurality of external input terminals, detects an intermediate voltage of the selection external input terminal, and outputs an interrupt processing signal related to the detection of the intermediate voltage to the CPU core section.
