Bit6
P0.7 (/WR), P0.6 (/RD), and P0.5 (ALE) are ‘skipped’ by the Crossbar and their output
states are determined by the Port latches and the External Memory Interface.
P0.7 (/WR) and P0.6 (/RD) are ‘skipped’ by the Crossbar and their output states are
determined by the Port latches and the External Memory Interface.
