Operation Mode Summary
The commands described previously can be grouped into four different categories to make clearer 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 from 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.
