Notes:
In PWM mode, the value to be written to the Output Compare Register is first transferred to a
temporary location, and then latched into the OCR when the Timer/Counter reaches $FF. This
prevents the occurrence of odd-length PWM pulses (glitches) in the event of an unsynchronized
OCR0 or OCR2 write. See
