Notes:
1. If the data bus is externally buffered and/or level translated, this write data hold time will be increased by the propagation
These timings are based on default settings and required initial programming. These timings may be modified via the MMS
Memory Wait State 1 Register, Index 62h, and the Command Delay Register, Index 60h. (See the Élan
