Abstract
Data in an EEPROM contained in a microcomputer integrated circuit device is erased and re-writing. Upon a detection of a start bit of the data, data of a plurality of bits is accepted in a shift register in response to a clock signal applied from a synchronization circuit. A counter counts clock signals up to the number corresponding to the data of a plurality of bits to inhibit data writing in the shift register. The data accepted in the shift register is temporarily stored as bit parallel data of a plurality of bits in a receiving buffer and selected by a selector to be applied to the EEPROM. The data is written, by a write control circuit, at an address in the EEPROM designated by an address counter.
