pwm control thru software currently i am using the microcontroller with external eprom in order to drive the dc motor with direction i use the pulse width modultion thru software control assembly language programming however i am afraid that they will be overheads and thus alter the pulse timing my question is is the software pwm control reliable i understand that port is a latch and so i vary the duty cycle by setting it high first and at the desire duty cycle then i set low any improments
