Table 262. TIM internal input/output signals

General-purpose timers (TIM2/TIM3/TIM4/TIM5)
Signal type
Timer multi-purpose channels.
Each channel be used for capture, compare,
or PWM.
TIM_CH1 and TIM_CH2 can also be used
as external clock (below 1/4 of the
Input/Output
tim_ker_ck clock) , external trigger and
quadrature encoder inputs.
TIM_CH1, TIM_CH2 and TIM_CH3 can be
used to interface with digital hall effect
sensors.
External trigger input. This input can be
used as external trigger or as external clock
Input source. This input can receive a clock with a
frequency higher than the tim_ker_ck if the
tim_etr_in prescaler is used.
Signal type
Internal timer inputs bus. These inputs can
be used for capture or as external clock
Input
(below 1/4 of the tim_ker_ck clock) and for
quadrature encoder signals.
External trigger internal input bus. These
inputs can be used as trigger, external clock
or for hardware cycle-by-cycle pulse width
Input
control. These inputs can receive clock with
a frequency higher than the tim_ker_ck if the
tim_etr_in prescaler is used.
Internal trigger input bus. These inputs can
be used for the slave mode controller or as a
Input
input clock (below 1/4 of the tim_ker_ck
clock).
Internal trigger output. This trigger can
Output
trigger other on-chip peripherals.
Timer tim_ocref_clr input bus. These inputs
can be used to clear the tim_ocxref signals,
Input
typically for hardware cycle-by-cycle pulse
width control.
Input Timer APB clock.
