Table 45. TIM2 alternate function remapping
Alternate function
TIM2_REMAP[1:
0] = “00” (no
remap)
TIM2_REMAP[1:
0] = “01” (partial
remap)
TIM2_REMAP[1:
0] = “10” (partial
remap)
(1)
1. Remap not available on 36-pin package.
TIM2_REMAP[1:
0] = “11” (full
remap)
(1)
TIM2_CH1_ETR
(2)
2. TIM_CH1 and TIM_ETR share the same pin but cannot be used at the same time (which is why we have
this notation: TIM2_CH1_ETR).
