Documentation of Module SYSTEM

Post by Marc » Mon Oct 22, 2018 8:25 am

Hi,

according the Cortex-M4 examples, the procedure SYSTEM.VMSR(0) is invoked, which seems to be an assembler equivalent for the unmapped FPSCR register.
Sadly this procedure is not documented somewhere , so I'm asking myself are there more undocumented instances like this ?

Regards,
Marc

Any features like this that you may discover are not documented because they are not supported for general use. Any that are used in the source code have only been tested for that specific purpose. Feel free to experiment to find out more but be aware that you use them elsewhere at your own risk.
