NOTES: 1. RD timing has the same timing as DS, LDS, UDS, and PSEN signals.
2. RD and PSEN have the same timing for 80C51XA.
3. Any input used to select an internal PSD4135G2V 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, LDS, and UDS signals.
