    E2 Emulator 1. Outline Outline Features of the E2 emulator The E2 emulator is an on-chip debugging emulator that includes a flash programming function, which is used for debugging and programming programs to be embedded in microcontrollers that have on-chip flash memory. That is, the product can be used for both debugging programs while the target microcontroller is connected to the user system, and to write programs to the on-chip flash memory of microcontrollers.

Connecting the Emulator and User System 2.3.4 Connecting the RESET pin While you are using the E2 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 E2 emulator fixes the RESET pin to the low level before the debugger is activated.
  • Page 13 For power supply from the E2 emulator, precision is not guaranteed. When writing a program that requires reliability, do not use the power supply function of the E2 emulator. Use a stable, separate power supply for the user system. When writing a program for mass production processes, use the Renesas Flash Programmer. WARNING Warning for Turning the Power On/Off: When supplying power, ensure that there are no shorts between the user system and power circuit.
  • Page 14 2.3.8 Small connector conversion adapter A small connector conversion adapter (R0E000010CKZ11) is separately available from Renesas for user system boards which are too small to mount the 14-pin connector that is the standard connector for the E2 emulator. By using the adapter, you can reduce the area taken up by the connector mounted on your system.

    E2 Emulator 4. Functional overview Software tracing (LPD output) Devices of the RH850 family support debugging instructions for the output of software trace data. Software trace data are stored in the internal trace memory of the device and output to the emulator via the LPD pins, which is the debugging- connection interface.

    E2 Emulator 5. Notes on Usage Notes on Usage Cautionary notes on using the E2 emulator are given below. General cautionary notes 5.1.1 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.

    Set the MOSC_40MHz bit of OPBT7 according to the input frequency of the main OSC. The initial value of the MOSC_40MHz bit is 1 (40 MHz). When the input frequency of the main OSC is 20 MHz, set the MOSC_40MHz bit to 0 (20 MHz) by the Renesas Flash Programmer (RFP).

  • Page 24: Notes On Differences In Operation Between The Actual Device And The Emulator

    E2 Emulator 5. Notes on Usage Notes on differences in operation between the actual device and the emulator 5.3.1 Serial programming function The serial programming function cannot be used with the emulator during debugging. 5.3.2 Current drawn The target device draws more current when an emulator is connected than when it is not. That is, the target device consumes more power while it is connected an emulator than while it is not, since the debugging circuit is operating.
  • Page 25 E2 Emulator 5. Notes on Usage 5.3.5 Executing a program in the initially stopped state after a reset When a reset is applied while a debugger is connected, it forcibly releases all CPUs from their initially stopped states and places them in the break state, regardless of whether the debugger is in the synchronous debugging mode or asynchronous debugging mode.

  • Page 26: Cautionary Notes On Debugging

    E2 Emulator 5. Notes on Usage Cautionary notes on debugging 5.4.1 Power to the target system while debugging Do not turn the power to the target system off during debugging. Doing so will require reconnection of the debugger. 5.4.2 OTP flag Do not set the one-time programming (OTP) flag in self-programming with the emulator.
  • Page 27 E2 Emulator 5. Notes on Usage suppressed in response to the inhibition of MDP exceptions may be detected when an access event is set without data comparison but not detected when an access event is set with data comparison. 5.4.8 The order of event detection In the following cases, since the orders of instructions and event detection may not operate as set, to measure the time or performance in sequential events, section tracing, and desired sections may not be possible.
  • Page 28 E2 Emulator 5. Notes on Usage 5.4.13 Stepped execution of the HALT mode and the HALT instruction A break leads to release from HALT mode. When a HALT instruction is encountered during single step execution (execution in units of assembly instruction), a break is set at the next instruction following the HALT instruction, and the mode does not change to the HALT mode.

  • Page 30 E2 Emulator 5. Notes on Usage 5.4.17 Rewriting of on-chip flash memory (modifying the clock settings) The debugger temporarily changes the clock settings (the PLL is selected with no frequency division) to improve the speed of processing while the flash memory is being rewritten* and restores the previous clock settings after this processing.
  • Page 31 E2 Emulator 5. Notes on Usage 5.4.22 Cautionary points on asynchronous debugging mode In the asynchronous debugging mode, peripheral break functions cannot be used. Even if peripheral break functions are enabled, peripheral functions are not stopped. In the asynchronous debugging mode, when any of CPUs is in the break state, no user system resets are acceptable. During execution of a user program, there may be a case that the ECC error function does not normally operate for flash memory.
  • Page 32 E2 Emulator 5. Notes on Usage 5.4.24 Cautionary points regarding external trigger input/output When external trigger input or external trigger output functions are in use, access to memory during the execution of a program, changes to event conditions, the reading of internal trace memory, and the display of state indicators such as STOP are disabled.
