Circuit structure for starting the operation of a data bus has a comparator linked to a reset circuit signal and a circuit to give a pulse to start the data bus linking a processor to many users.

摘要

A circuit for generating a pulse starts the operation of a data bus that links a processor to multiple users having user areas and drivers with bus-hold circuits. The output for a comparator (7) links to a reset signal for a reset circuit (9) so that a monostable flip-flop (8) receives a signal from the comparator only during a switch-on routine. An Independent claim is also included for a method for starting the operation of a data bus linking a processor to multiple users.
