Force Output Compare for Channel A
Force Output Compare for Channel B
The FOC0A/FOC0B bits are only active when the WGM0[3:0] bits specifies a non-PWM mode. When writing a logical one to the FOC0A/FOC0B bit, an immediate compare match is forced on the Waveform Generation unit. The OC0A/OC0B output is changed according to its COM0x[1:0] bits setting. Note that the FOC0A/FOC0B bits are implemented as strobes. Therefore it is the value present in the COM0x[1:0] bits that determine the effect of the forced compare.
A FOC0A/FOC0B strobe will not generate any interrupt nor will it clear the timer in Clear Timer on Compare match (CTC) mode using OCR0A as TOP. The FOC0A/FOC0B bits are always read as zero.
