STM32F103C8T6 'interrupt pin' How do I use it?

1. MCU : STM32F103C8T6
2. BOOT : https://github.com/rogerclarkmelbourne/ ... _pc13.bin/

I would like to use a hardware 'interrupt pin'.
I'd like to know how.
help me.

If we take Arduino as an example,
https://www.arduino.cc/reference/ko/lan ... interrupt/

I would like to use the interrupter like this:
In terms of hardware, I would like to implement an event to be activated every time a HIGH signal is received.

I've not tried it, but that apparently STM 'official' core may have that
https://github.com/stm32duino/Arduino_C ... /tree/main
https://github.com/stm32duino/Arduino_C ... terrupts.h
https://github.com/stm32duino/Arduino_C ... rrupts.cpp

it would help to review the codes and the ref manual under EXTI while using it
https://www.st.com/resource/en/referenc ... ronics.pdf
EXTI is a hardware feature, hence review that to understand how it works.
