This defines the frequency used to sample the TI4 input, f
filter applied to TI4. The digital filter requires N consecutive samples in the same state before
being output.

Note: PCLK is 12 MHz when using the 24 MHz crystal oscillator, and 6 MHz using the 12 MHz
00: No prescaling, capture each time an edge is detected on the capture input.
01: Capture once every 2 events.
10: Capture once every 4 events.
11: Capture once every 6 events.
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 TI4.
10: Channel is an input and is mapped to TI3.
11: Channel is an input and is mapped to TRGI. This mode requires an internal trigger input
selected by the TIM_TS bit in the TIMx_SMCR register.
Note: TIM_CC2S may be written only when the channel is off (TIM_CC2E = 0 in the
