Expand description

Clock prescaler for PWM

The prescaler dictates the PWM frequency, together with the IO clock. The formula is as follows:

F_pwm = CLK_io / (Prescaler * 256);
Prescaler16 MHz Clock8 MHz Clock
Direct62.5 kHz31.3 kHz
Prescale87.81 kHz3.91 kHz
Prescale64977 Hz488 Hz
Prescale256244 Hz122 Hz
Prescale102461.0 Hz30.5 Hz

Variants

Direct

No prescaling, the IO clock drives the timer directly.

Prescale8

Divide the IO clock by 8.

Prescale64

Divide the IO clock by 64.

Prescale256

Divide the IO clock by 256.

Prescale1024

Divide the IO clock by 1024.
