Note:
• Bit 1:0 – WGMn1:0: Waveform Generation Mode
Combined with the WGMn[3:2] bits found in the TCCRnB 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 three types of Pulse Width Modulation (PWM) modes.
