OC2E
Output Compare 1 Pin Enable
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.
Output Compare 2 Pin Enable
This bit is used only to output the signal from the timer on the OCMP2 pin (OLV2 in
Output Compare mode). Whatever the value of the OC2E bit, the Output Compare 2
function of the timer remains active.
0: OCMP2 pin alternate function disabled (I/O pin free for general-purpose I/O).
1: OCMP2 pin alternate function enabled.
R/W
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.
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.
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.
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.
The OLVL1 bit is copied to the OCMP1 pin whenever a successful comparison
occurs with the OC1R register and the OC1E bit is set in the CR2 register.
