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.
