CC2640: How to enter privileged mode

Viki Shi

Part Number: CC2640

Hi Team,

As the user's guide shows, there's some register that can only be accessed in privileged mode. So how to enter the privileged mode?

Best regards,

Hi Viki,

I'm assuming you are referring to ARM Cortex-M3 privileged mode.

Here is the TI-RTOS explanation:

processors.wiki.ti.com/.../BIOS_for_Stellaris_Devices

Within SYS/BIOS:

Swi and Task threads run in 'Thread' mode.

Hwi threads run in 'Handler' mode.

All SYS/BIOS internal code as well as application code (ie Hwi, Swi, and Task threads) run in 'Privileged' code mode.

For performance reasons, SYS/BIOS does NOT support 'User' code mode.

Best wishes
