STC15W4K32S4 series microcontroller has 6 high precision PWM, that is, PWM2, PWM3, PWM4, PWM5, PWM6, PWM7. PWM waveform generator for each PWM and designed two is used to control the waveform flip counter T1 and T2, each PWM control can be very flexible to the high level and the low level of PWM width, duty ratio and PWM output control delay.
