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 cal-
culated by following equation
