• Bits 5:4 – Res: Reserved Bits
• Bit 3 – WGM02: Waveform Generation Mode
• Bits 2:0 – CS02:0: Clock Select
Read/Write
Initial Value
The FOC0A 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
FOC0A bit, an immediate Compare Match is forced on the Waveform Generation unit. The
OC0A output is changed according to its COM0A1:0 bits setting. Note that the FOC0A bit
is implemented as a strobe. Therefore it is the value present in the COM0A1:0 bits that
determines the effect of the forced compare.
A FOC0A strobe will not generate any interrupt, nor will it clear the timer in CTC mode
using OCR0A as TOP.
The FOC0A bit is always read as zero.
The FOC0B 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
FOC0B bit, an immediate Compare Match is forced on the Waveform Generation unit. The
OC0B output is changed according to its COM0B1:0 bits setting. Note that the FOC0B bit
is implemented as a strobe. Therefore it is the value present in the COM0B1:0 bits that
determines the effect of the forced compare.
A FOC0B strobe will not generate any interrupt, nor will it clear the timer in CTC mode
using OCR0B as TOP.
The FOC0B bit is always read as zero.
These bits are reserved bits in the Atmel
zero.
