CHAPTER 3 DIFFERENCES BETWEEN TARGET DEVICES
When emulating the target device with IE-78044-R-EM and IE-78000-R, the operations for the target device slightly
differ from those for the actual device. This chapter describes these differences.
3.1 Setting Mask Option
Settings for the mask option resistors P3, P7*, P8, P9, P10, P11, and P12* can be changed by using the screen
debugger (SD78K0) or the DIP switch on IE-78044-R-EM.
3.1.1 Setting mask option with screen debugger (SD78K0)
(1) P3
P3 is a CMOS I/O pin that can be connected to a pull-down resistor. Whether the pull-down resistor is connected
or not can be selected on the configuration panel of the screen debugger.
(2) P7*
P7 is N-ch open-drain pins, that can be connected to a pull-up resistor. Note that P7 is a medium-voltage pin that
can withstand +15 V. To connect or disconnect a pull-up resistor to these pins, use the configuration panel for
the screen debugger.
(3) P0
The P0/XT1 pin is a multiplexed pin and can be used as a port pin or a subsystem clock input pin. The function
for this pin can be switched by the screen debugger configuration panel.
