Bit 5 CC2P: Capture/Compare 2 output polarity
Refer to CC1P description
Bit 4 CC2E: Capture/Compare 2 output enable
Refer to CC1E description
Bit 3 CC1NP: Capture/Compare 1 complementary output polarity
Note: This bit is not writable as soon as LOCK level 2 or 3 has been programmed (LOCK bits
On channels having 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.
Bit 2 CC1NE: Capture/Compare 1 complementary output enable
On channels having a complementary output, this bit is preloaded. If the CCPC bit is set in the
TIMx_CR2 register then the CC1NE active bit takes the new value from the preloaded bit only
when a Commutation event is generated.
Bit 1 CC1P: Capture/Compare 1 output polarity
Note: This bit is not writable as soon as LOCK level 2 or 3 has been programmed (LOCK bits
802/1454
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 and TI2FP1. Refer
to CC1P description.
in TIMx_BDTR register) and CC1S="00" (channel configured as output).
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.
0: OC1 active high (output mode) / Edge sensitivity selection (input mode, see below)
1: OC1 active low (output mode) / Edge sensitivity selection (input mode, see below)
When CC1 channel is configured as input, both CC1NP/CC1P bits select the active polarity
of TI1FP1 and TI2FP1 for trigger or capture operations.
CC1NP=0, CC1P=0: 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 or encoder
mode).
CC1NP=0, CC1P=1: 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 or encoder mode).
CC1NP=1, CC1P=1: non-inverted/both edges/ The circuit is sensitive to both TIxFP1 rising
and falling edges (capture or trigger operations in reset, external clock
or trigger mode), TIxFP1is not inverted (trigger operation in gated
mode). This configuration must not be used in encoder mode.
CC1NP=1, CC1P=0: The configuration is reserved, it must not be used.
in TIMx_BDTR register).
On channels having 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.
