differ from those for the actual device. This chapter describes these differences.
3.1 Setting Mask Option
debugger (SD78K0) or the DIP switch on IE-78044-R-EM.
3.1.1 Setting mask option with screen debugger (SD78K0)
When emulating the target device with IE-78044-R-EM and IE-78000-R, the operations for the target device slightly
Settings for the mask option resistors P3, P7*, P8, P9, P10, P11, and P12* can be changed by using the screen
(1) P3
(2) P7*
(3) P0
*:
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.
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.
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.
PD78024 Subseries is not provided with this port.
