For the pin where stated as N.C. in the table, leave the signal unconnected.
*1: Input/output is based on the target system.
*2: To debug, MPMD pin needs to be brought to Low state.
Shown in the target connection reference diagram is the circuit that brings MPMD pin to Low state when you connect MPMD signal to the connector for debugger.
If you do not connect MPMD signal to Pin No. 4 of the connector for debugger, the circuit that sets MPMD pin by switch circuit will do. However, in such case, do not
connect MPMD pin to Pin No. 4 of the connector for debugger, but connect Pin No. 4 of connector for the debugger to GND..
*3: For VCC, connect I/O power of CPU. Debugging can be performed even if the signal is N.C., however, by connecting I/O power, leak during
the target system power OFF can be prevented.

(For detailed dimensions of the connector,
refer to the documentatio by manufacturer of the connector.)
*Please look at the pin configuration diagram above and make
sure that the connector is in the right direction before connecting.
Please check the pin number in the signal table above and make sure
the signal and the pin numbers match.
*1:
PRESET, which is connected to Pin No. 13 of the connector for debugger, is the signal that debugger uses for monitoring the state of PRESET
pin of CPU.
