TCCR1B – Timer/Counter Control Register B
Bit 7 – FOCnA: Force Output Compare A
The FOCnA bit is only active when the WGM bits specify a non-PWM mode.
However, for ensuring compatibility with future devices, this bit must be set to zero when
TCCRnB is written when operating in PWM mode. When writing a logical one to the FOCnA bit,
an immediate Compare Match is forced on the Waveform Generation unit. The OCnA output is
changed according to its COMnA[1:0] bits setting. Note that the FOCnA bit is implemented as a
strobe. Therefore it is the value present in the COMnA[1:0] bits that determines the effect of the
forced compare.
A FOCnA strobe will not generate any interrupt, nor will it clear the timer in CTC mode using
OCRnA as TOP.
The FOCnA bit is always read as zero.
Bit 6 – FOCnB: Force Output Compare B
The FOCnB bit is only active when the WGM bits specify a non-PWM mode.
However, for ensuring compatibility with future devices, this bit must be set to zero when
TCCR0B is written when operating in PWM mode. When writing a logical one to the FOCnB bit,
an immediate Compare Match is forced on the Waveform Generation unit. The OCnB output is
changed according to its COMnB[1:0] bits setting. Note that the FOCnB bit is implemented as a
strobe. Therefore it is the value present in the COMnB[1:0] bits that determines the effect of the
forced compare.
A FOCnB strobe will not generate any interrupt, nor will it clear the timer in CTC mode using
OCRnB as TOP.
The FOCnB bit is always read as zero.
Bits 5:4 – Res: Reserved Bits
These bits are reserved and will always read zero.
Bit 3 – WGMn2: Waveform Generation Mode
