All ,
as i am working on PWM generation in MIOS,
i just wanted to know what is the minimum & the maximum frequency range that can be used to generate the PWM waves using MIOS module in MPC565.
From the user manual of MPC565 , frequency for generation of waves can be done by
system clk = 40Mhz
clock prescalar range is 1 to FF(as per MPC565 manual)
System Clk
Frequency (for PWM) = --------------------------------
CP
for CP = 1,
40Mhz
Maximum Frequency = ------------ = 40Mhz
1
40Mhz
Minimum Frequency = ------------ = 157 khz (approx)
(FF)= (255)
Please let me know with appropriate reply for my query
Advanced thnx
