In the following figure, The six consecutive addresses must be READ in the order listed in the
must be HIGH during all six consecutive cycles.
In the following figure, this is the amount of time it takes to take action on a soft sequence command. Vcc power must remain
HIGH to effectively register the command. Commands such as STORE and RECALL lock out IO until operation is complete which
further increases this time. See the specific command.
