Bit Description
5:0 : level
needed for nested interrupt support
software writes current vector number to this register, so only interrupts with
higher priority (lower vector number) can nest.

Bit Description
MIE
Main interrupt enable flag which can be used for easy implementation of cli() and sei()
routines.
Note: cli() usually must check (save current enable status) and then clear interrupt enable
flag atomic (non interruptable). EL16 has no such operation, so GIE flag cannot be used.
GIE should only be used for interrupt nesting. When MIE is only used inside cli() and sei(),
cli() must not save current status, because MIE is always enabled on cli() entry.
