Hi, I am working on a project using EXTI interrupts from the GPIO pins on the STM32F303 Discovery Board. I am using the STM32F03x_StdPeriph_Driver and CMSIS libraries.
In these libraries EXTI 1-16 are defined, while for the EXTI IRQn interrupt handlers 0-4 are defined, as well as 9_5 and 15_10. Which interrupt handler is meant to work with each EXTI Line? Is it possible to have the 9_5 line handle interrupts from multiple lines? Say from both 6 and 7?
