Table 36. PWM Outputs OCR1x = $00 or OCR1C, x = A or B
In PWM mode, the Timer Overflow Flag – TOV1, is set as in normal Timer/Counter
mode. Timer Overflow Interrupt1 operates exactly as in normal Timer/Counter mode,
i.e., it is executed when TOV1 is set provided that Timer Overflow Interrupt and global
interrupts are enabled. This also applies to the Timer Output Compare flags and
interrupts.
The frequency of the PWM will be Timer Clock 1 Frequency divided by (OCR1C
value + 1). See the following equation:
Resolution shows how many bit is required to express the value in the OCR1C Register.
It is calculated by following equation
