・ 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,

ASEMD0 pin needs to be brought to Low state.

Shown in the target connection reference diagram is the circuit that brings ASEMD0 pin to Low state when you connect ASEMD0 signal to the connector for

debugger.

If you do not connect ASEMD0 signal to Pin No. 4 of the connector for debugger, the circuit that sets ASEMD0 pin by switch circuit will do. However, in such case,

do not connect ASEMD0 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.

*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.

*2:

ASEBRKAK/ASEBRK (Output/Input signals) are multiplexed with FWE (Input signal) in a pin. To allow the operation of the user target alone

when you use the ICE, in making signal arrangement, do not connect the pin to VCC nor GND directly, but connect it to a pull-up resistor with

ohmic value of 4.7K or a pull-down resistor with ohmic value of 100k.
