NOTES: 1. RD timing has the same timing as DS and PSEN signals.
2. RD and PSEN have the same timing for 80C51.
3. Any input used to select an internal PSD835G2V function.
4. In multiplexed mode latched address generated from ADIO delay to address output on any Port.
5. RD timing has the same timing as DS.
