    I've not tried this but i'd read the interrupt set enable registers - see the Cortex M3 Technical Reference:8.2.2

    Hello,

    I was wondering if there is a way to know which interrupt is enabled or not.

    For example, I enable a few interrupt such as USART1, CAN_RX, ... using the NVIC_Init from the ST library. After that, I would like something returning a mask of interrupt enabled or not. I haven't seen a ST library function having this possibility.

    I was thinking of reading the register, but I haven't found the address of this register in any document. By debugging the library I saw that the register modified is at the address 0xE000E000. But this one is in a reserved section refering to the memory map in document RM0008.

    Does anybody have an idea or know how to check all interrupt enabled?

    Thanks in advance.

    Thank you Giles.

    I can read the register at the address 0xE000E100. It gives me back properly which interrupt is enabled.
