1.
There are additional registers in Spec.A as following table. These are used for
additional function in Spec.A, software pull-up resister,Serial I/O2 and
an increase of analog input pin number .
When not using the additional functions in Spec.A, take the following (1) or (2)
(1) Don’t write any data to the additional registers(or bit). (Keep the initial state
after releasing Reset)
(2) Write the initial state to the additional registers(or bit) after releasing Reset

• If in the program for Standard ver. any data have been not written to the addresses
corresponding to the Spec.A’s additional registers, this program can be used for
Spec.A as it is (not requiring to change program codes).
