Dear I.MX community,

 

Could you please let me know how can we get to know what is the MAX PWM output freq, I see in page number  2487 in i.mx6ull applns referemce manual

 

PWMO (Hz) = PCLK(Hz) / (period +2)

PCLK  is 12 bit prescalaer max input freq is 66MHz

 

66MHz/2^12 = 16113.28125 which is 16Khz

 

May I know what is the period value??

 

Assuming period to be 0 is the mAX pwm out freq is 8Khz???

 

Could you please let me know what is the max pwm output freq is it 8Khz and what is the maximum ONTIME  and offtime??

 

Kindly do the needful as early as possible

Many Thanks in advance
