Table 51B. Write, Erase and Program Timing (3 V Range)
Note: 1. Any input used to select an internal M88x3Fxx FLASH+PS D function.
2. In multiplexed mode, latched address generated from ADIO delay to address output on any port.
3. WR has the same timi ng as E, DS, LDS, UDS, WRL, and WRH signals.
4. Assuming data is stable before active write signal.
5. Assuming write is active before data becomes valid.
6. TWHAX2 is the address hold time for DPLD inputs that are used to generate chip selects for internal PSD memory.
