Smart Config. : PWM

The PWM (pulse width modulation) output function is timer that generate multiple PWM outputs by using a master and multiple slave channels.
The pulse cycle (frequency) is set in the master channel.
The pulse width (duration) is set in the slave channel.

Smart Config. : PWM formula

MCU clock src : 40M ,
clock div : 40M / 2^6 = 625K Hz ,
target freq : 100Hz = 10000 us

period : 1/100 (which is 10000us) = (val_m + 1 ) * (1/ 625K)

=> val_m : 625K/100 – 1 = 6250 – 1 = 6249 (0x1869)

duty(%) = val_s / (val_m + 1) *100 , 50/100 = val_s/(val_m + 1)
=> val_s = (1/2)*6250 = 3125 (0xC35)

duty(%) = val_s / (val_m + 1) *100 , 75/100 = val_s/(val_m + 1)
=> val_s = (3/4)*6250 = 4687.5 (0x1250)
