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.
