This configures the channel as an output or an input. If an input, it selects the input source.
00: Channel is an output.
01: Channel is an input and is mapped to TI3.
10: Channel is an input and is mapped to TI4.
11: Channel is an input and is mapped to TRGI. This requires an internal trigger input selected
by the TIM_TS bit in the TIM_SMCR register.
Note: TIM_CC3S may be written only when the channel is off (TIM_CC3E = 0 in the
If CC4 is configured as an output channel:
0: OC4 is active high.
1: OC4 is active low.
If CC4 configured as an input channel:
0: IC4 is not inverted. Capture occurs on a rising edge of IC4. When used as an external
trigger, IC4 is not inverted.
0: IC4 is inverted. Capture occurs on a falling edge of IC4. When used as an external trigger,
IC4 is inverted.
1: Capture is enabled.
If CC4 is configured as an output channel:
0: OC4 is disabled.
1: OC4 is enabled.
If CC4 configured as an input channel:
0: Capture is disabled.
1: Capture is enabled.
