MPU Configuration

Hello Team,

I am working on ARM Cortex-M3 processor based MCU and I would like to separate the software on different section based on MPU configuration using MCUXpresso Configuration tool.

So i'm thinking about different section in flash memory. But, I need to protect this section, software item A should not interact with software item B.

So I understand region configuration and MPU configuration but I don't understand Access Permission. (Priviliged and Unprivileged). Moreover, I wanted to know about read only and R/W memory protection.

For example: If I configure the region 0 (flash memory) as read only, would it be possible to change R/W for region 0 after sometime or would it be only one time process?

Kindly let me know if any reference document available.
