・ 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,

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. 22 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. 22 of the connector for debugger, but connect Pin No. 22 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.

*4: It is used as an output signal as PALMiCE does not support RAM monitor function.

(Pin Configuration)

(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.

*: When using the pins multiplexed with AUDMD or AUDRST signal, do not enable AUDMD nor AUDRST signal in Pin Function Controller.

When the debugger is used, neither AUDMD nor

AUDRST signal is to be used; set the CPU to AUD trace mode. If you enable AUDMD or

AUDRST signal, it will inevitably change the setting of AUD.

*1:

RES, which is connected to Pin No. 31 of the connector for debugger, is the signal that debugger uses for monitoring the state of RES pin of

CPU.
