Re: How to switch the access privilage control modes in Aurix tc39xx microcontroller

Hello,

You could make use of the Program Status Word (PSW) Register . Please note that a CPU must access its own CSFR registers using MTCR and MFCR instructions.
You could refer to CPUx Program Status Word Register description in the AURIXTC3XX_um_part1_v2.0 User Manual.

Regards,
Aiswarya.
