I know that the HSEM has been deprecated on the MP2x family of MPUs. However, it still appears to be supported, given that there is an entire chapter (22) dedicated to it in the user manual, as well as having some space carved out for it in the CUBE setup, though those options seem to be disabled. My question is, has anyone used the HSEM on an MP2 MCU, and if so, how is this accomplished? This all came about from a need to raise a *simple* interrupt between cores, without the latency and overhead of OpenAMP, the RIF, remoteproc, etc., etc. It seems straightforward enough, but if the MP2 does not support HSEM, then why is it presented in the manual as though it does? This makes no sense. I have had a couple of people tell me that HSEM is not preferred (okay, fine) but nobody has been able to explain why the documentation at least suggests it can be used, whatever its favored status. Thanks to anyone who can shed some light. It seems unbelievable that this beast of a micro has no was to send a simple EXTI between cores.
