Notes:
In the PWM mode, the 8, 9 or 10 least significant OCR1A/OCR1B bits (depends of resolution),
when written, are transferred to a temporary location. They are latched when Timer/Counter1
reaches the value TOP. This prevents the occurrence of odd-length PWM pulses (glitches) in
the event of an unsynchronized OCR1A/OCR1B write. See
example in each mode.
