STMG4 Where is the control register - Cant find it in the documentation!

Tobe · ‎2023-12-11

It is really frustrating to not find an information, even worse, you always have to login again with writing your full emailadress, while you checked "save login" before!

Here is what i am looking for (this is all i found as register for privilege mode):

The register CONTROL is one from the core Cortex-M4, which is documented in PM0214, section 2.1.3. The CONTROL register is handled like the other core registers with CMSIS, where you can find references to it. More detailed documentation can be found at developer.arm.com, e.g. in dui0553.

Hope that helps?

Good luck!

As this is part of the CPU core, it's not covered in the RM but the PM, in this case PM0214 for Cortex-M4. Or check any book or documention for the M4-*core*.

It should be stated, that this is a core register, and any information can be found at xxx.

Some might know about this details, but some newcomers dont know.

Newcomers should not start with reading RM or DS, but with literature about ARM-Cortex-M family in general, i.e. something like "The Definitive Guide to ARM Cortex-M3 and Cortex-M4 Processors". This will give some insight about the whole family and even help to select the appropriate chip for the given task.
