Timer/Counter1 can also be used as an 8-, 9- or 10-bit Pulse Width Modulator. In this
mode the counter and the OCR1A/OCR1B Registers serve as a dual glitch-free stand-
alone PWM with centered pulses. Refer to page 53 for a detailed description of this
function.
The Input Capture function of Timer/Counter1 provides a capture of the Timer/Counter1
contents to the Input Capture Register (ICR1), triggered by an external event on the
Input Capture pin – PD4/(IC1). The actual capture event settings are defined by the
Timer/Counter1 Control Register (TCCR1B). In addition, the Analog Comparator can be
set to trigger the Input Capture. Refer to “Analog Comparator” on page 75 for details on
this. The ICP pin logic is shown in Figure 34.
