Bit 7 = ICIE Input Capture Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the
Bit 6 = OCIE Output Compare Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is generated whenever the
Bit 5 = TOIE Timer Overflow Interrupt Enable.
0: Interrupt is inhibited.
1: A timer interrupt is enabled whenever the TOF

1: Forces the OLVL2 bit to be copied to the
Bit 3 = FOLV1 Forced Output Compare 1.
0: No effect.
1: Forces OLVL1 to be copied to the OCMP1 pin.
Bit 2 = OLVL2 Output Level 2.
This bit is copied to the OCMP2 pin whenever a
successful comparison occurs with the OC2R reg-
ister and OC2E is set in the CR2 register. This val-
ue is copied to the OCMP1 pin in One Pulse Mode
and Pulse Width Modulation mode.
Bit 1 = IEDG1 Input Edge 1.
This bit determines which type of level transition
on the ICAP1 pin will trigger the capture.
0: A falling edge triggers the capture.
1: A rising edge triggers the capture.
Bit 0 = OLVL1 Output Level 1.
The OLVL1 bit is copied to the OCMP1 pin when-
ever a successful comparison occurs with the
OC1R register and the OC1E bit is set in the CR2
register.
