These bits control the Output Compare pin (OC0B) behavior. If one or both of the
COM0B1:0 bits are set, the OC0B output overrides the normal port functionality of the I/O
pin it is connected to. However, note that the Data Direction Register (DDR) bit correspond-
ing to the OC0B pin must be set in order to enable the output driver.
When OC0B is connected to the pin, the function of the COM0B1:0 bits depends on the
WGM02:0 bit setting.
bits are set to a normal or CTC mode (non-PWM).
