Reset Exception
Priority and handler addresses for events
The Reset exception is generated when the reset input line to the CPU is asserted. The Reset
exception can not be masked by any bit. The Reset exception resets all synchronous elements
and registers in the CPU pipeline to their default value, and starts execution of instructions at
address 0x8000_0000.
