This bit-field defines the direction of the channel (input/output) as well as the used input.
00: CC2 channel is configured as output
01: CC2 channel is configured as input, tim_ic2 is mapped on tim_ti2
10: CC2 channel is configured as input, tim_ic2 is mapped on tim_ti1
11: CC2 channel is configured as input, tim_ic2 is mapped on tim_trc. This mode is working
only if an internal trigger input is selected through the TS bit (TIMx_SMCR register)
Note: CC2S bits are writable only when the channel is OFF (CC2E = ‘0’ in TIMx_CCER).
Bit 7 OC1CE: Output compare 1 clear enable
0: tim_oc1ref is not affected by the tim_ocref_clr_int signal
1: tim_oc1ref is cleared as soon as a High level is detected on tim_ocref_clr_int signal
(tim_ocref_clr input or tim_etrf input)
