Hello.
I'm reading the nrf51 Reference Manual. in MPU section, [ (SWD) will no longer have access to code region 0 or code region 1, as well as no longer being able to access RAM or any peripherals except for the NVMC.]
I wonder why can not access the memory areas are SWD. I want to know why need this functionality.
I hope you'll teach this point.
regards.
