Nothing is assigned.

In an attempt to write to these bits, write “0”. The value, if read, turns out to be “0”.

The corresponding port is pulled

high with a pull-up resistor

0 : Not pulled high

1 : Pulled high

0 : Imput mode

(Functions as an input port)

1 : Output mode

(Functions as an output port)

Nothing is assigned.

These bits can neither be set nor reset. When read, their contents are

indeterminate.

Note 1: This bit can only be accessed for reset (= 0), but cannot be accessed for set (= 1).

Note 2: To rewrite the interrupt control register, do so at a point that dose not generate the

interrupt request for that register. For details, see the precautions for interrupts.
