In period 2 and period 4, new Duty (TC0R) is set, but the PWM output waveform of period 2 and period 4 are wrong. In
period 2, the new TC0R value is greater than old TC0R value. If setting new TC0R is after PWM output “low”, system is
getting TC0C < TC0R result and making PWM output “high”. There are two high level periods in the cycle, and the
waveform is unexpected. Until next cycle, PWM outputs correct duty. In period 4, the new TC0R value is smaller than
the old TC0R value. If setting new TC0R is before PWM output “low”, system is getting TC0C

≧

TC0R result and

making PWM output “low”. In the cycle, the high duty is shorter than last cycle and longer than correct cycle. It is an
unexpected PWM output.

Though the wrong waveforms only exist in one cycle, it is still a problem for precise PWM application and might make
outside loading operations error. The solution is to load new TC0R after TC0 timer overflow. Using TC0IRQ status to
determine TC0 timer is overflow or not. When TC0IRQ becomes “1”, to set the new TC0R value into TC0R buffer, and
the unexpected PWM output is resolved.

Example: Using TC0 interrupt function to set new TC0R value for changing PWM duty.
