This bit selects whether ETR or the inverse of ETR is used for trigger operations.
0: ETR is non-inverted, active at a high level or rising edge.
1: ETR is inverted, active at a low level or falling edge.
This bit enables external clock mode 2.
0: External clock mode 2 disabled.
1: External clock mode 2 enabled. The counter is clocked by any active edge on the ETRF
signal.
Note: Setting the TIM_ECE bit has the same effect as selecting external clock mode 1 with
External trigger signal ETRP frequency must be at most 1/4 of CK frequency. A prescaler can
be enabled to reduce ETRP frequency. It is useful with fast external clocks.
00: ETRP prescaler off.
01: Divide ETRP frequency by 2.
10: Divide ETRP frequency by 4.
11: Divide ETRP frequency by 8.

mode, gated mode and trigger mode. TRGI must not be connected to ETRF in this case
(the TIM_TS bits must not be 111).
If external clock mode 1 and external clock mode 2 are enabled at the same time, the
external clock input will be ETRF.
It is possible to use this mode simultaneously with the following slave modes: reset
