There are additional registers in Spec.A as following table. These are used for additional function in Spec.A, software pull-up resister 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 Additional Registers in Spec.A Address 001216 001316 001416 003716 Spec.A Port P0P1P2 pull-up control register Port P3 pull-up control register Port P4 pull-up control register Analog input selection register Spec.H Reserved Reserved Reserved Reserved • If in the program for Spec.H any data have been not written to the additional registers’ addresses which are reserved in Spec.H, this program can be used for Spec.A as it is (not requiring to change program codes).

When not using the additional functions, it is possible to develop program using M38517RSS 3. In Spec.A,the built-in pull-up resisters can be used for termination of unused pins. 4. There are differences in electric characteristics,operation margin,noise immunity and noise radiation between Spec.A and Spec.H due to the difference in the manufacturing processes. When manufacturing an application system with Spec.H switching to use of Spec.A, please perform sufficient evaluations for the commercial samples of Spec.A Mask ROM version.

Renesas Electronics assumes no liability whatsoever for any damages incurred by you resulting from errors in or omissions from the information included herein. Renesas Electronics products are classified according to the following three quality grades: “Standard”, “High Quality”, and “Specific”. The recommended applications for each Renesas Electronics product depends on the product’s quality grade, as indicated below. You must check the quality grade of each Renesas Electronics product before using it in a particular application. You may not use any Renesas Electronics product for any application categorized as “Specific” without the prior written consent of Renesas Electronics. Further, you may not use any Renesas Electronics product for any application for which it is not intended without the prior written consent of Renesas Electronics. Renesas Electronics shall not be in any way liable for any damages or losses incurred by you or third parties arising from the use of any Renesas Electronics product for an application categorized as “Specific” or for which the product is not intended where you have failed to obtain the prior written consent of Renesas Electronics. The quality grade of each Renesas Electronics product is “Standard” unless otherwise expressly specified in a Renesas Electronics data sheets or data books, etc. Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic equipment; and industrial robots. “High Quality”: Transportation equipment (automobiles, trains, ships, etc.); traffic control systems; anti-disaster systems; anticrime systems; safety equipment; and medical equipment not specifically designed for life support. “Specific”: Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or systems for life support (e.g. artificial life support devices or systems), surgical implantations, or healthcare intervention (e.g. excision, etc.), and any other applications or purposes that pose a direct threat to human life. You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics, especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, installation and other product characteristics. Renesas Electronics shall have no liability for malfunctions or damages arising out of the use of Renesas Electronics products beyond such specified ranges. Although Renesas Electronics endeavors to improve the quality and reliability of its products, semiconductor products have specific characteristics such as the occurrence of failure at a certain rate and malfunctions under certain use conditions. Further, Renesas Electronics products are not subject to radiation resistance design. Please be sure to implement safety measures to guard them against the possibility of physical injury, and injury or damage caused by fire in the event of the failure of a Renesas Electronics product, such as safety design for hardware and software including but not limited to redundancy, fire control and malfunction prevention, appropriate treatment for aging degradation or any other appropriate measures. Because the evaluation of microcomputer software alone is very difficult, please evaluate the safety of the final products or system manufactured by you.
