The Command Interface only uses A–1, A0-A10 and DQ0-DQ7 to verify the commands; A11-A20, DQ8-DQ14 and DQ15 are Don’t
Care. DQ15A–1 is A–1 when BYTE is V
2. Sampled, but not 100% tested.
3. Maximum value measured at worst case conditions for both temperature and V
4. Maximum value measured at worst case conditions for both temperature and V
