I/O pin it is connected to. However, note that the Data Direction Register (DDR) bit correspond-
ing 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 depen-
dent of the WGMn3:0 bits setting. Table 29 shows the COMnx1:0 bit functionality when the
WGMn3:0 bits are set to a Normal or a CTC mode (non-PWM).
Table 30 shows the COMnx1:0 bit functionality when the WGMn3:0 bits are set to the fast PWM
mode.
Note:
1. A special case occurs when OCRnA/OCRnB equals TOP and COMnA1/COMnB1 is set. In
this case the compare match is ignored, but the set or clear is done at TOP. See “Fast PWM
Mode” on page 109. for more details.
Table 31 shows the COMnx1:0 bit functionality when the WGMn3:0 bits are set to the phase cor-
rect or the phase and frequency correct, PWM mode.
