■CONNECTED SPECIFICATION OF MB91401 AND ICE
Recommended type and circuit configuration of the emulator interface connector mounting on the user system, attention when designing and wiring regulation are shown.
When the flat cable is used, the combination of the connectors with housing should be selected.
