Question about VICProtection

Dear All,

In firmware for USBiZi, is the VICProtection register enabled (set to 1) to prevent user code or RLP from accessing VIC registers?

VICProtection register can only be accessed in system mode or supervisor mode. Is there anyway to enter system mode or supervisor mode from RLP? As I know, only exception or interrupts can switch user mode to other mode. so if RLP is in user mode, there is no way to switch to other modes.

Thanks a lot,

Best wishes,
