(Operation explanation)
Provision in runaway of program by noise mixing.
Write operation to specified SFR is prohibited so that provision program in
And error handling in runaway becomes easy by INTP0 interruption.

executed with protection on state.
A state of protection can be confirmed by reading EMCCR0<PROTECT>.
By reset, protection becomes OFF.
And INTP0 interruption occurs when write operation to specified SFR was
