  • Page 14 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. CAUTION Turning the Power On/Off: When supplying power, ensure that there are no shorts between the user system and power circuit.

    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). 5.2.4 Cases where connecting the debugger is not possible It is not possible to start debugging if the target device is in any of the following states (this also applies in cases where hot plug-in connection is in use).

    E2, IE850A 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.

    E2, IE850A 5. Notes on Usage Cautionary notes on debugging 5.4.1 Power to the user system while debugging Do not turn the power to the user 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.

Notes on Usage 5.4.14 Masking of resets while the emulator is in use Table 5-1 shows the state of a device while the emulator is in use and the operation of resets issued by the user system or the user program (i.e. user system reset). During single stepping, resets are masked to emulate each step in the source code of the program in non-realtime.

Notes on Usage 5.4.15 Masking of interrupts while the emulator is in use Table 5-2 shows the states of a device while the emulator is in use and the operation of interrupts (EIINT, FEINT, or FENMI). During single stepping, interrupts are masked to emulate each line of source code of the program in non-realtime.

  • Page 35 Trace-full break [IE850A] In external tracing, trace data are stored in the trace memory in the IE850A. The emulator requests a break in execution by the target device before the trace memory becomes full (trace-full break). If the request is not accepted immediately, the output of trace data may continue even after the trace memory is full and data will thus be lost.
  • Page 36 E2, IE850A 5. Notes on Usage 5.4.29 Breakpoints in the code flash P/E mode or data flash P/E mode During debugging of a user program which makes the target device enter the code flash P/E mode or data flash P/E mode, we recommend using hardware breakpoints rather than software breakpoints.
