0: One Pulse Mode is not active.
1: One Pulse Mode is active, the ICAP1 pin can be used to trigger one pulse on the
OCMP1 pin; the active transition is given by the IEDG1 bit. The length of the
generated pulse depends on the contents of the OC1R register.
0: PWM mode is not active.
1: PWM mode is active, the OCMP1 pin outputs a programmable cyclic signal; the
length of the pulse depends on the value of OC1R register; the period depends on
the value of OC2R register.
The timer clock mode depends on these bits (see
This bit determines which type of level transition on the ICAP2 pin will trigger the
capture.
0: A falling edge triggers the capture.
1: A rising edge triggers the capture.
This bit determines which type of level transition on the external clock pin EXTCLK
will trigger the counter register.
0: A falling edge triggers the counter register.
1: A rising edge triggers the counter register.
