• Bit 7:6 – COMnA1:0: Compare Output Mode for channel A
• Bit 5:4 – COMnB1:0: Compare Output Mode for channel B
The COMnA1:0 and COMnB1:0 control the Output Compare pins (OCnA and OCnB
respectively) behavior. If one or both of the COMnA1:0 bits are written to one, the OCnA
output overrides the normal port functionality of the I/O pin it is connected to. If one or
both of the COMnB1:0 bit are written to one, the OCnB output overrides the normal port
functionality of the I/O pin it is connected to. However, note that the Data Direction Reg-
ister (DDR) bit corresponding to the OCnA or OCnB pin must be set in order to enable
the output driver.
When the OCnA or OCnB is connected to the pin, the function of the COMnx1:0 bits is
dependent of the WGMn3:0 bits setting. Table 53 shows the COMnx1:0 bit functionality
when the WGMn3:0 bits are set to a normal or a CTC mode (non-PWM).
