These bits control the Output Compare pin (OC2B) behavior. If one or both of the
COM2B1:0 bits are set, the OC2B output overrides the normal port functionality of the I/O
pin it is connected to. However, note that the Data Direction Register (DDR) bit corre-
sponding to the OC2B pin must be set in order to enable the output driver.
When OC2B is connected to the pin, the function of the COM2B1:0 bits depends on the
WGM22:0 bit setting.
WGM22:0 bits are set to a normal or CTC mode (non-PWM).
