I am trying to set the TMPL (Thread Mode Privilige Level) bit on the CONTROL register, but I do not know how to access it. I tried accessing the register in assembly and it gave me an error. I couldn't find how to do it in the data sheet.

Thank you.

Here is a simple C function (that uses the asm() function) to change a thread to unPrivileged.

void unPrivileged(void)
{
    asm(" mov r0, #1");
    asm(" msr CONTROL, r0");
}
