To our customers, Old Company Name in Catalogs and Other Documents On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology Corporation, and Renesas Electronics Corporation took over all the business of both companies. Therefore, although the old company name remains in this document, it is a valid Renesas Electronics document. We appreciate your understanding. Renesas Electronics website: http://www.renesas.
Notice 1. 2. 3. 4. 5. 6. 7. All information included in this document is current as of the date this document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas Electronics products listed herein, please confirm the latest product information with a Renesas Electronics sales office.
To all our customers Regarding the change of names mentioned in the document, such as Hitachi Electric and Hitachi XX, to Renesas Technology Corp. The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.) Accordingly, although Hitachi, Hitachi, Ltd.
User’s Manual Connection of H8S/2377F and H8S/2377RF User’s Manual HS2378KCM01H HS2378KCI01H with E10A Emulator www.renesas-electoronics.com Version 1.
1. Connecting the E10A Emulator with the User system Before connecting an E10A emulator (here after referred to as emulator) with the user system, a connector must be installed in the user system so that an user I/F cable can be connected to the connector. When designing the user system, refer to the connector and recommended circuits shown below. Before designing the user system, be sure to read the H8S/2378F E10A user’s manual.
2. Installation of Connector in the User System Table 2.1 shows the Hitachi-UDI port connector for the emulator. Table 2.1 Recommended Connector Type Number Manufacturer Specifications 2514-6002xx* 3M Limited 14-pin straight type Note: xx means plated version. Note: When the connector is used, do not install any components within 3 mm of the Hitachi-UDI port connector.
3. Pin Arrangement of the H-UDI Port Connector Figure 3.1 shows the pin arrangement of the Hitachi-UDI port connector. Figure 3.
4. Example of Emulator Connection The following shows an example of connecting the user system to the emulator. Figure 4.
Notes: 1. #WDTOVF, P53, and PG4 to PG6 are used by the emulator for H8S/2377F and H8S/2377RF. Pull up and connect the emulator and MCU pins. Peripheral functions that are shared by those pins cannot be used. Figure 4.2 Connection of Emulator and MCU 2. Pin EMLE of the H8S/2377F and H8S/2377RF must be pulled up before connecting the emulator to the user system. If the emulator is not connected to the user system, ground pin EMLE. Figure 4.
3. #RES of pin 4 of the Hitachi-UDI port connector is a signal line in which the emulator outputs signals to the MCU. An AND operation must be performed between #RES and the user system reset circuit for the signal line connected to the MCU. #RES of pin 7 of the Hitachi-UDI port connector is a signal line in which the emulator monitors the #RES signal of the MCU. The #RES must be pulled up before it is connected to pin 7 of the Hitachi-UDI port connector. Figure 4.4 Examples of Reset Circuits 4.
7. When H8S/2377F and H8S/2377RF are connected to the emulator, I/O functions of P53 and PG4 to PG6 , and functions of #WDTOVF, #IRQ3, #ADTRG, #BREQ, #BACK, and #BREQ0 cannot be used. The symbol (#) means that the signal is active-low.
