Operation Mode Summary
The commands described previously can be grouped into four different categories to better describe which commands
can be executed at what times.
Group A commands consist of:
Group B commands consist of:
Group C commands consist of:
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.
Most of the commands in Group B can be suspended and resumed, except the Buffer Transfer, Buffer Compare, and
Auto Page Rewrite operations. If a Group B command is suspended, all of the Group A commands can be executed. See
