Unable to find vague reference to other technical documentation.

Hi,

I am trying to sort out an interrupt problem on an STM32F4 board. I have RM0090 Reference manual which is rather cursory on the subject and refers me to another document: All interrupts including the core exceptions are managed by the NVIC. For more information on exceptions and NVIC programming see Chapter 5: Exceptions & Chapter 8: Nested Vectored Interrupt Controller in the ARM CortexTM-M4F Technical Reference Manual. There seem to be a multitude of documents with similar titles with notably different content and so far I have not been able to find anything with relevant chapters indicated in this note. Where can I find this document? Thanks.

Likely from an older and restricted document, basically the ARM TRM

The Cortex-M3 TRM has similar Chaptering, and frankly content in this regard.

The current M4 one in PDF here

ST has a version of these in it's Programming Manual (PM) series. You might be better describing the actual problem, there are a number of hazards related to interrupt exiting and clearing.

Hi,

You can have a look to this
