(1) when starting the integrated debugger, set as follows. table 1-2. settings when integrated debugger is started item when emulating m pd78070a when emulating m pd78070ay cpu series 78078 78078y internal rom size (kb) in mapping setting area of configuration dialog box 0 internal ram size (bytes) in mapping setting area of configuration dialog box 1024 also, set the target memory in the mapping setting area of the configuration dialog box. a setting example is shown below. example 1. when external rom (32 kb) is used for the target system target 0000, 7fff example 2. when the internal memory of the ie-78k0-ns is used as virtual rom (32 kb) (when target system is not used) emulation rom 0000, 7fff (2) during execution of the integrated debugger reset command, only pins a0 to a7 of the dedicated pins for accessing external rom (ad0 to ad7, a0 to a15, rd, and wr) are set to port mode. this is because in the IE-78078-NS-EM1, the value of the external bus type selection register (ebts) becomes 00h after reset (the value becomes 0h1 for the actual m pd78070a and 78070ay). table 1-3. value after reset of ebts item when emulating m pd78070a when emulating m pd78070ay value after ebts reset 01h (separate bus mode) 00h (multiplexed bus mode) be sure to set ebts to 01h prior to program execution, using the procedure shown below. chapter 1 general users manual u14741ej1v0um00 17 <1> execute cpu reset. <2> change the value of ebts in the sfr window from 00h to 01h. <3> execute the program via the run panel. note that the value of ebts becomes 00h by the reset performed by watchdog timer mode 2 of the watchdog timer (reset is triggered when an overflow occurs) and by the target system (the reset signal is input to reset), therefore these operations cannot be emulated. (3) the following special function registers not included in the m pd78070a and 78070ay are displayed, but these registers should be ignored. p4, p5, p8, pm5, pm8, and krm users manual u14741ej1v0um00 18 [memo] users manual u14741ej1v0um00 19 chapter 2 part names this chapter introduces the parts of the IE-78078-NS-EM1 main unit. the packing box contains the emulation board (IE-78078-NS-EM1), packing list, users manual, and guarantee card. if there are any missing or damaged items, please contact an nec sales representative. fill out and return the guarantee card that comes with the main unit. chapter 2 part names users manual u14741ej1v0um00 20 2.1 parts of main unit figure 2-1.

(1) clock that is already mounted on emulation board (2) clock that is mounted by user (3) external clock if the target system includes an internal clock, select either (1) clock that is already mounted on emulation board or (2) clock that is mounted by user. for an internal clock, a resonator is connected to the target device and the target devices internal oscillator is used. an example of the external circuit is shown in part (a) of figure 3-2. during emulation, the resonator that is mounted on the target system is not used. instead, the clock that is mounted on the emulation board installed for the ie-78k0-ns is used. if the target system includes an external clock, select (3) external clock. for an external clock, a clock signal is supplied from outside the target device and the target devices internal oscillator is not used. an example of the external circuit is shown in part (b) of figure 3-2. caution the ie system will be hung-up if the main system clock is not supplied normally. moreover, be sure to input a rectangular wave as the clock from the target. the ie system does not operate if the crystal resonator is connected to x1 (main system clock) and xt1 (subsystem clock). figure 3-2. external circuits used as system clock oscillator (a) internal clock (b) external clock x2 or xt2 x2 or xt2 target device target device external clock x1 or xt1 x1 or xt1 chapter 3 installation users manual u14741ej1v0um00 24 (1) clock that is already mounted on emulation board (a) for main system clock a crystal oscillator (x1) is already mounted on the emulation board. its frequency is 5.0 mhz. figure 3-3. when using clock that is already mounted on emulation board (main system clock) remark the clock that is supplied by the IE-78078-NS-EM1s oscillator (encircled in the figure) is used.
