• Bit 3:2 – COM3C1:0 - Compare Output Mode for Channel C
The COM3C1:0 bits control the output compare behavior of pin OC3C. If one or both of
the COM3C1:0 bits are written to one, the OC3C output overrides the normal port
functionality of the I/O pin it is connected to. However note that the Data Direction
Register (DDR) bit corresponding to the OC3C pin must be set in order to enable the
output driver. When the OC3C is connected to the pin, the function of the COM3C1:0
bits is dependent of the WGM33:0 bits setting. The following table shows the
COM3C1:0 bit functionality when the WGM33:0 bits are set to a normal or a CTC mode
(non-PWM). For the other functionality refer to section "Modes of Operation".
Table 18-14 COM3C Register Bits
• Bit 1:0 – WGM31:30 - Waveform Generation Mode
Combined with the WGM33:2 bits found in the TCCR3B Register, these bits control the
counting sequence of the counter, the source for maximum (TOP) counter value, and
what type of waveform generation to be used. Modes of operation supported by the
Timer/Counter unit are: Normal mode (counter), Clear Timer on Compare match (CTC)
mode, and three types of Pulse Width Modulation (PWM) modes. For more information
on the different modes see section "Modes of Operation".
