Bit 7 CC2NP: Capture/Compare 2 complementary output polarity
Bit 6 CC2NE: Capture/Compare 2 complementary output enable
Bit 5 CC2P: Capture/Compare 2 output polarity
Bit 4 CC2E: Capture/Compare 2 output enable
Bit 3 CC1NP: Capture/Compare 1 complementary output polarity
Note: On channels having a complementary output, this bit is preloaded. If the CCPC bit is

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.
