Method and device for controlling a number of output signals in a microprocessor with a time base

摘要

A method and device for controlling the time sequence of a number of output signals in a microprocessor by means of only one timer, particularly for the real-time parallel output of a number of signals with different switching-on and switching-off times for controlling the operation of an internal combustion engine, in which the switching-off times are determined by the fact that at the beginning of in each case an interrupt determined by the timer (timer interrupt - second interrupt level) a check is made as to how many of the at least three different signals to be output are to be switched off in the next intermediate timer interrupt interval by determining the switching-off time intervals by means of associated comparison registers and that a priority-related switching-off order is determined. <IMAGE>
