2. In multiplexed mode, latched address generated from ADIO delay to address output on any port.
3. WR has the same timing as E, 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 Sector Select signals for internal PSD memory.
