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
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
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 the following bits:
00: timer clock = f
01: timer clock = f
10: timer clock = f
11: timer clock = external clock (where available)
Note: If the external clock pin is not available, programming the
external clock configuration stops the counter.
