・ 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: 2 routings of AUD ports are available. Choose either of them.

*3: To debug,

ASEMD pin needs to be brought to Low state.

Shown in the target connection reference diagram is the circuit that brings ASEMD pin to Low state when you connect ASEMD signal to the connector for

debugger. If you do not connect ASEMD signal to Pin No. 3 of the connector for debugger, the circuit that sets ASEMD pin by switch circuit will do. However, in

such case, do not connect ASEMD pin to Pin No. 3 of the connector for debugger, but connect Pin No. 3 of connector for the debugger to GND.

*4: For VCC_AUD, the power same as the voltage level at which AUD signal of CPU works is to be connected. Connect the AUD signal to I/O

power of CPU.

*5: For VCC, the power same as the voltage level at which HUDI signal of CPU works is to be connected. Connect the HUDI signal to I/O power

of CPU.

*6: By detection of GND on the target system side, whether the target system is connected or not is determined.

Manufacturer AMP

Model Mictor connector

2-767004-2 / 767054-1 / 767061

(Top view on the target board)

(For detailed dimensions of the connector,

refer to the documentation 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: RES, which is connected to Pin No. 9 of the connector for debugger, is the signal that debugger uses for monitoring the state of RES pin of

CPU.
