These bits are reserved bits in the ATA6602/ATA6603 and will always read as zero.
Combined with the WGM02 bit found in the TCCR0B Register, these bits control the count-
ing sequence of the counter, the source for maximum (TOP) counter value, and what type of
waveform generation to be used (see
Timer/Counter unit are: Normal mode (counter), Clear Timer on Compare Match (CTC)
mode, and two types of Pulse Width Modulation (PWM) modes (see
