TCCR0B – Timer/Counter0 Control Register B
• Bits 1:0 – WGM01:0: Waveform Generation Mode
Combined with WGM03:2 bits of TCCR0B, these bits control the counting sequence of the coun-
ter, the source for maximum (TOP) counter value, and what type of waveform to generate. See
Table
ter), Clear Timer on Compare match (CTC) mode, and three types of Pulse Width Modulation
(PWM) modes.
Table 11-5.
• Bit 7 – ICNC0: Input Capture Noise Canceler
Setting this bit (to one) activates the Input Capture Noise Canceler. When the noise canceler is
activated, the input from the Input Capture pin (ICP0) is filtered. The filter function requires four
successive equal valued samples of the ICP0 pin for changing its output. The Input Capture is
therefore delayed by four oscillator cycles when the noise canceler is enabled.
• Bit 6 – ICES0: Input Capture Edge Select
This bit selects which edge on the Input Capture pin (ICP0) that is used to trigger a capture
event. When the ICES0 bit is written to zero, a falling (negative) edge is used as trigger, and
when the ICES0 bit is written to one, a rising (positive) edge will trigger the capture.
