i do not know how to control epwm channels.
now epwm1(master) is linked to epwm2(salve), ans epwm3(master) is liked to epwm4(salve)
i want to turn on epwm3 and epwm4 when finsh epwm1 and epwm2 pulse.
after the number of pulse of epwm1 and epwm2, they turn off the pulse and than immediately turn on epwm3 and epwm 4.
for turning off the epwm 1 and 2, i used interrupt to count the number of pulse.
who have any idea?
i change epwm1~7 enable register. but it is not right way.
