Abstract
A microcomputer is realized having a built-in SIO which is able to correspond to a LAN which requires strict timing control and also correspond to a high speed serial communication. A counter supplies.a clock signal for data shift to an SIO register which performs serial-parallel conversion and vice versa. Two D flip-flop circuits detect the rise of an SRDY signal, an input signal expressing the start of transmission, and give the counter a reset signal.
