I work on a timer application for a STM32F103 MCU. The goal is to time pulse signals. My question: what timer input channels are connected to what GPIO pins (PA.02, etc.)? I assume there is a table in some ST doc. Can you please point me to one? Thanks!

The datasheet has this info:

You can also bring up the chip in STM32CubeMX and look at the functions for each pin. Sometimes this is more convenient.

Thank you, @TDK​ ! I found it and am using the table. RPK created a nice graphical representation of all pin functions (reblag.dk/stm32). Enjoy.

Nice, and also incorrect in details, e.g. there are no TIM2_CHxN channels, some functions on the left hand side noted as alternative even if they are native, and MHz is written incorrectly.
