15. Command Tables

AT45DB321D
Group D commands consist of:
If a Group A command is in progress (not fully completed), then another command in Group A,
B, C, or D should not be started. However, during the internally self-timed portion of Group B
commands, any command in Group C can be executed. The Group B commands using buffer 1
should use Group C commands using buffer 2 and vice versa. Finally, during the internally self-
timed portion of a Group D command, only the Status Register Read command should be
executed.
