Bit Name

Function

Timer Overflow Interrupt Enable

5 TOIE 0: Interrupt is inhibited.

1: A timer interrupt is enabled whenever the TOF bit of the SR register is set.

Forced Output compare 2

4 FOLV2

This bit is set and cleared by software.

0: No effect on the OCMP2 pin.

1: Forces the OLVL2 bit to be copied to the OCMP2 pin, if the OC2E bit is set and

even if there is no successful comparison.

Forced Output compare 1

t(s) 3 FOLV1

This bit is set and cleared by software.

0: No effect on the OCMP1 pin.

1: Forces OLVL1 to be copied to the OCMP1 pin, if the OC1E bit is set and even if

there is no successful comparison.

uc Output Level 2

Prod 2 OLVL2

This bit is copied to the OCMP2 pin whenever a successful comparison occurs with

the OC2R register and OCxE is set in the CR2 register. This value is copied to the

OCMP1 pin in One Pulse mode and Pulse Width modulation mode.

te Input Edge 1

bsole 1 IEDG1

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.

- O Output Level 1

) 0 OLVL1 The OLVL1 bit is copied to the OCMP1 pin whenever a successful comparison

t(s occurs with the OC1R register and the OC1E bit is set in the CR2 register.

Bit Name

Function

Output Compare 1 Pin Enable

7 OCIE

This bit is used only to output the signal from the timer on the OCMP1 pin (OLV1 in

Output Compare mode, both OLV1 and OLV2 in PWM and One-Pulse mode).

Whatever the value of the OC1E bit, the Output Compare 1 function of the timer

remains active.

0: OCMP1 pin alternate function disabled (I/O pin free for general-purpose I/O).

1: OCMP1 pin alternate function enabled.
