Atmel ATmega16/32/64/M1/C1
Timer/Counter1 Control Register B – TCCR1B
• Bit 7 – ICNCn: 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 (ICPn) is filtered. The filter function requires
four successive equal valued samples of the ICPn pin for changing its output. The Input Cap-
ture is therefore delayed by four Oscillator cycles when the noise canceler is enabled.
• Bit 6 – ICESn: Input Capture Edge Select
This bit selects which edge on the Input Capture pin (ICPn) that is used to trigger a capture
event. When the ICESn bit is written to zero, a falling (negative) edge is used as trigger, and
when the ICESn bit is written to one, a rising (positive) edge will trigger the capture.
When a capture is triggered according to the ICESn setting, the counter value is copied into
the Input Capture Register (ICRn). The event will also set the Input Capture Flag (ICFn), and
this can be used to cause an Input Capture Interrupt, if this interrupt is enabled.
When the ICRn is used as TOP value (see description of the WGMn3:0 bits located in the
TCCRnA and the TCCRnB Register), the ICPn is disconnected and consequently the Input
Capture function is disabled.
• Bit 5 – RTGEN
Set this bit to enable the ICP1A as a timer/counter retrigger input.
(This bit is reserved for future use. For ensuring compatibility with future devices, this bit must
be written to zero when TCCRnB is written.)
• Bit 4:3 – WGMn3:2: Waveform Generation Mode
See TCCRnA Register description.
• Bit 2:0 – CSn2:0: Clock Select
The three Clock Select bits select the clock source to be used by the Timer/Counter, see
ure 13-10
Table 13-5.
