• Bit 3:2 – Reserved Bits
These bits are reserved for future use.
• Bit 1:0 – WGM11:0: Waveform Generation Mode
Combined with the WGM13:2 bits found in the TCCR1B Register, these bits control the counting
sequence of the counter, the source for maximum (TOP) counter value, and what type of wave-
form generation to be used, see

of Pulse Width Modulation (PWM) modes.
