WRITING CONTROLLER FOR EEPROM

摘要: PURPOSE:To prevent the miswriting when runaway is generated in a soft and an incorrect memory address specified by executing writing/reading in/from EEPROM only output from time width signal generating means. CONSTITUTION:An I/O CPU 1 applied at timing (a) consideration of execution time. The decoded decoder DE2, to chip select terminal one-shot multiplexer M1 generates (c) WR same timing. A gate circuit G1 finds out coincidence between 1, M1, 2. Even if E error, can be suppressed.
