Remark When the IE-789835-NS-EM1 is shipped, the settings for “when using clock that is already mounted on
No hardware settings are required for this situation.
When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select “External” in
the area (Clock) for selecting the CPU’s clock source (this selects the user’s clock).
When the IE-789835-NS-EM1 is shipped, a 32.768 kHz crystal resonator (XTC1) and the parts board (X2) on
which pins 6 and 8 are shorted are already mounted on the IE-789835-NS-EM1. Short the 2 to 3 side on the IE-
789835-NS-EM1’s jumper (JP2). There is no need to make any other settings via the integrated debugger
(ID78K0S-NS).
The settings described under either (a) or (b) are required, depending on the type of clock to be used. Short the
2 to 3 side on the IE-789835-NS-EM1’s jumper (JP2).
