Hi there..

Currently i am using a 68230 PI/T to interface between my electric devices and the 68000 motorola microprocessor. I am facing the problem on how to input something from my device to the microprocessor through 68230. My device will sends a +5V to indicate HIGH and 0V to indicate LOW.

Is there anyone know how to configure the 68230 to read input? I have tried some approaches but all give unexpected results.

Need help urgently..Thanks in advance..
