Table 65. Read Timing
Note: 1. RD timing has the same timing as DS, LDS, UDS, and PSEN signals.
2. RD and PSEN have the same timing for 8031.
3. Any input used to select an internal PSD 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.
