hi,
 
i'm having a hard time understanding the purpose of the SYS instruction. this is supposed to an MPU call. is this an interrupt call where you can enter supervisor state? how about when i want to set the descriptors for XGATE code execution, how do do it?
 
there is also interrupt vectors for access errors ?
