How can I interface P89LPC932 @ 3V and SJA1000 @ 5V ? Can output of P89LPC932 drives input of SJA1000 , /CS /RD /WR /ALE directly ? I use P0 port of P89LPC932 as Data Bus between LPC932 and SJA1000. can they drive each other ? Can /int pin of SJA1000 drives LPC932 ? SJA1000 uses Power Up Reset, So /rst doesnt consider. Thx for advice.
