1). For 8-bit operation : P0.0 - P0.7 for data and P3.2, P3.3 & P3.4 for RS, RW and E. Will I have problem with Port O as it is an open drain type ?. Will I need pull ups resistor for P0 ?.

2). For 4-bit operation : P0.4 - P0.7 for data and P3.2, P3.3 & P3.4 for RS, RW and E. Same question as above.

Thanks,
SGH
