(Note)
Nothing is assigned.
In an attempt to write to these bits, write “0.” The value, if read, turns out to
be indeterminate.
Notes 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).
2: To rewrite the interrupt control register, do so at a point that does not generate the
interrupt register for that register. For details, see the precautions for interrupts.

Nothing is assigned.
In an attempt to write to these bits, write “0.” The value, if read, turns out to
be indeterminate.
Notes 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).
2: Bit 4 at address 0049 16 is invalid. Must always be set to “0.”
3: To rewrite the interrupt control register, do so at a point that does not generate the
interrupt register for that register. For details, see the precautions for interrupts.
