Cortex-M Exception Handling (Part 2)

Ivan Cibrario Bertolotti ● February 1, 2016●9 comments

The first part of this article described the conditions for an exception request to be accepted by a Cortex-M processor, mainly concerning the relationship of its priority with respect to the current execution priority. This part will describe instead what happens after an exception request is accepted and becomes active.

Before discussing in detail the sequence of actions that occurs within the processor after an exception request...
