Figure 10-5. Example of PWM
PWM function can be implemented by using the TCMPBn. PWM frequency is determined by TCNTBn. Figure 10-
5 shows a PWM value determined by TCMPBn.
For a higher PWM value, decrease the TCMPBn value. For a lower PWM value, increase the TCMPBn value. If
an output inverter is enabled, the increment/decrement may be reversed.
The double buffering function allows the TCMPBn, for the next PWM cycle, written at any point in the current
PWM cycle by ISR or other routine.
