General-purpose timers (TIM15/16/17) RM0351
978/1693 DocID024597 Rev 3
Note: The state of the external I/O pins connected to the complementary OCx and OCxN channels
depends on the OCx and OCxN channel state and AFIO registers.
Bit 0 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

bits must be kept cleared.
