Note that the Data Direction Register (DDR) bit corresponding to the OC1B pin must be set in
order to enable the output driver.
The function of the COM1B1:0 bits depends on the PWM1B and WGM10 bit settings.

• Bit 3 - FOC1A: Force Output Compare Match 1A
The FOC1A bit is only active when the PWM1A bit specify a non-PWM mode.
Writing a logical one to this bit forces a change in the Waveform Output (OCW1A) and the Out-
put Compare pin (OC1A) according to the values already set in COM1A1 and COM1A0. If
COM1A1 and COM1A0 written in the same cycle as FOC1A, the new settings will be used. The
Force Output Compare bit can be used to change the output pin value regardless of the timer
value.
