Notes

15. Read and Write cycles in progress before HSB

is asserted are given this minimum amount of time to complete.

16. This is the amount of time that it takes to take action on a soft sequence command. Vcc power must remain high to effectively register command.

17. Commands like Store and Recall lock out I/O until operation is complete which further increases this time. See specific command.
