ABSTRACT:
The AD conversion control section of the processor sets the clock generating circuit of the output port alternately to an L-level output condition and an H-level output condition to generate a clock signal. A chip select signal is caused to be output from the chip select circuit of the output port in synchronization with output of the first clock signal by the interruption signal. Furthermore, the bit data output in series bit by bit from the AD converter in synchronization with occurrence of a clock signal is incorporated bit by bit in synchronization with the interruption signal from the input ports to be stored in the register.
