Emulator Additional Document for User’s Manual (this manual). The additional document is for a particular set of MCUs (in this case, MCUs of the RH850/E1L and RH850/E1M-S groups). Be sure to read both of the manuals before using the E1 or E20 emulator. -
Page 5: Connecting The Emulator And User System
E1/E20 Emulator 2. Connecting the Emulator and User System Connecting the Emulator and User System To connect the E1 or E20 emulator, a connector for the user system interface cable must be mounted on the user system. When designing the user system, read this chapter of this manual and the hardware manual for the MCUs to be used. Connector mounted on the user system Table 2-1 shows the recommended connectors for connection of the E1 or E20 emulator. -
Page 6: Pin Assignments Of The Connector
E1/E20 Emulator 2. Connecting the Emulator and User System CAUTION Note on connector insertion and removal: When connecting or disconnecting the user-system interface cable and the emulator or user system, grasp the connector cover at the end of the cable. Pulling the cable itself will damage the wiring. Also, be aware that the user-system interface cable has the direction in which it must be inserted. -

Page 10: Connecting The Reset Pin
E1/E20 Emulator 2. Connecting the Emulator and User System 2.3.2 Connecting the RESET pin While you are using the E1 or E20 emulator, pin 13 (RESET pin) of the 14-pin connector must be connected to the reset pin of the target device. An example is shown in the figure below. The E1 or E20 emulator fixes the RESET pin to the low level before the debugger is activated. -
Page 11: Connecting The Tvdd Pin
E1/E20 Emulator 2. Connecting the Emulator and User System 2.3.3 Connecting the TVDD pin Power source monitoring function Connect the power source on the user system to pin 8 (TVDD pin) of the 14-pin connector. For the RH850/E1x series, this will be the source of the VCC voltage. The power source connected to the TVDD pin provides power to the final stage output buffer and first stage input buffer on the E1/E20 emulator circuit. -

Page 15: Notes On Usage
E1/E20 Emulator 4. Notes on Usage Notes on Usage Cautionary notes on using the E1 or E20 emulator are given below. Notes on differences in operation between the actual device and the E1 or E20 emulator No. 1 Cautionary note on the DBTRAP instruction The DBTRAP instruction is used for software breaks and thus cannot be used in programs with the emulator. - Page 16 E1/E20 Emulator 4. Notes on Usage No. 9 Operation in response to resets and interrupts when an emulator is in use When an emulator is in use, operation in response to resets and interrupts differs according to the specifications of the reset mask and interrupt settings, respectively, as shown in the tables below.

Page 17: Cautionary Notes On Debugging
E1/E20 Emulator 4. Notes on Usage Cautionary notes on debugging No. 1 Handling of devices which were used for debugging Do not use devices that were used for debugging in mass-production. This is because writing to the flash memory of such devices has already proceeded during debugging, so we cannot guarantee the number of times rewriting of the flash memory can proceed. - Page 18 E1/E20 Emulator 4. Notes on Usage of the E1 or E20 emulator session. No. 6 Initialization of RAM areas All RAM areas for use by a program must be initialized when an emulator is in use. Before the emulator is used, if any setting is made to initialize the RAM area when the emulator is started, ECC errors are not generated since the debugger initializes the RAM area.

- Page 20 E1/E20 Emulator 4. Notes on Usage No. 12 DEB bit of the MGDGRPROTn register When you are using an emulator, leave both the DEB bit of the MGDGRPROTn register and PROTDEB bit of the FSGDxxDPROTn register with the setting 1 (which allows access by a debug master). Changing either bit to a value other than its initial value may lead to normal access to memory becoming impossible.

No. 19 Access to I/O resources in the MCU Access to I/O resources (registers and RAM) in the MCU by the debugger (i.e. access through the memory or I/O register window) proceeds in the same way as access from a user program.
- Page 22 E1/E20 Emulator 4. Notes on Usage No. 22 Cautionary note on asynchronous debugging mode (peripheral break function) In the asynchronous debugging mode, peripheral break functions cannot be used. Even if peripheral break functions are enabled, peripheral functions are not stopped. No.
