*1: Input/output is based on the target system.
*2: RESIN is not a name of CPU pin. RESIN signal cannot be directly connected to CPU pin. For connection, consult the target connection
reference diagram.
*3: For VCC, connect I/O power of CPU. Debugging can be performed even if the signal is N.C., however, if you connect I/O power, it will allow
prevention of leak during the target system power OFF and adaptation to power 1.8V-3.6V range.
Note, for input, it is 5V-tolerant. If optional conversion adapter (ADP-HUDI-5V) is used, 5V is supported for output.
*4: PG4, PG5, PG6, P53 port functionality, other functionalities multiplexed in those pins, and functionalities of WDTOVF pin will not be
available since those pins are occupied by the debugger.

(For detailed dimensions of the connector,
refer to the documentation by manufacturer.)
*1: When debugging, bring EMLE pin to High state.
Shown in the target connection reference diagram is the circuit that brings EMLE pin to High state when you turn OFF the switch.
*2: RESIN, which is connected to Pin No.7 of the connector for debugger, is the signal that the debugger outputs to CPU. Connect the signal to
CPU by using user logic reset circuit with reference to the logic shown in the target connection reference diagram.
*3: RES, which is connected to Pin No. 13 of the connector for debugger, is the signal that debugger uses for monitoring the state of RES pin of
CPU.
