CC1E: Capture/Compare 1 output enable

CC1 channel configured as output:

0: Off OC1 is not active. OC1 level is then function of MOE, OSSI, OSSR, OIS1, OIS1N

and CC1NE bits.

1: On OC1 signal is output on the corresponding output pin depending on MOE, OSSI,

OSSR, OIS1, OIS1N and CC1NE bits.

CC1 channel configured as input:

This bit determines if a capture of the counter value can actually be done into the input

capture/compare register 1 (TIMx_CCR1) or not.

0: Capture disabled

1: Capture enabled

CC1P: Capture/Compare 1 output polarity

CC1 channel configured as output:

0: OC1 active high

1: OC1 active low

CC1 channel configured as input:

The CC1NP/CC1P bits select the polarity of TI1FP1 for trigger or capture operations…

00: Non-inverted/rising edge. The circuit is sensitive to TIxFP1 rising edge (capture or

trigger operations in reset, external clock or trigger mode), TIxFP1 is not inverted (trigger

operation in gated mode).

01: Inverted/falling edge. The circuit is sensitive to TIxFP1 falling edge (capture or trigger

operations in reset, external clock or trigger mode), TIxFP1 is inverted (trigger operation in

gated mode.

10: Reserved, do not use this configuration.

(capture or trigger operations in reset, external clock or trigger mode), TIxFP1 is not inverted

(trigger operation in gated mode).

Note: 1. This bit is not writable as soon as LOCK level 2 or 3 has been programmed (LOCK

bits in TIMx_BDTR register).

2. On channels that have a complementary output, this bit is preloaded. If the CCPC bit

is set in the TIMx_CR2 register then the CC1P active bit takes the new value from the

preloaded bit only when a Commutation event is generated.

1 (B_0x1): Non-inverted/both edges. The circuit is sensitive to both TIxFP1 rising and falling edges

CC1NE: Capture/Compare 1 complementary output enable

0: Off OC1N is not active. OC1N level is then function of MOE, OSSI, OSSR, OIS1, OIS1N

and CC1E bits.

1: On OC1N signal is output on the corresponding output pin depending on MOE, OSSI,

OSSR, OIS1, OIS1N and CC1E bits.

CC1NP: Capture/Compare 1 complementary output polarity

CC1 channel configured as output:

0: OC1N active high

1: OC1N active low

CC1 channel configured as input:

This bit is used in conjunction with CC1P to define the polarity of TI1FP1. Refer

to the description of CC1P.

Note: 1. This bit is not writable as soon as LOCK level 2 or 3 has been programmed (LOCK

bits in TIMx_BDTR register) and CC1S=‘00’ (the channel is configured in output).

2. On channels that have a complementary output, this bit is preloaded. If the CCPC bit

is set in the TIMx_CR2 register then the CC1NP active bit takes the new value from the

preloaded bit only when a commutation event is generated.
