3.5.1 Mask option settings
By setting the DIP switch (SW1) in the IE-789860-NS-EM1, a 33 k
Ω
pull-up resistor can be connected to P40 to
P43 by mask option.
Use the mask option setting dialog box of the integrated debugger (ID78K0S-NS) to set the mask option. When
reading a project file, however, setting is not required. The results of reading a project file are reflected in the mask
option setting dialog box.
For the usage method, refer to the
ID78K Series Ver.2.30 or Later Operation (Windows Based) User’s Manual
(U15185E)
.
