・ 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. 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.
*3: 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.
*4: 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.
*5: By detection of GND on the target system side, whether the target system is connected or not is determined.
*6: It is used as an output signal as PALMiCE does not support RAM monitor function.

(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.
*: 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. 9 of the connector for debugger, is the signal that debugger uses for monitoring the state of RES pin of
CPU.
