Table 50A. Read Timing (5 V Range)
Note: 1. RD timing has the same timing as DS, LDS, UDS, and PSEN signals.
2. RD and PSEN have the same timing.
3. Any input used to select an internal M88x3Fxx FLASH+P SD function.
4. In multiplexed mode, latched addresses generated from ADIO delay to address output on any Port.
5. RD timing has the same timing as DS, LDS, and UDS signals.
