Microcomputer for controlling electric motor

摘要

The microcomputer has a central processing unit (1) for setting the duration of the output pulses delivered to the electric motor, a clock source (2) counting clock pulses supplied to the microcomputer and a comparison register (3) for comparing the clock source output with the set duration for the control pulses. The output signal from the comparison register is fed to a masking circuit (4), providing an interrupt signal and an output time control signal for an output control circuit (5) delivering the control pulses to the motor.
