17. Read and Write cycles in progress before HSB are given this amount of time to complete.
18. This is the amount of time it takes to take action on a soft sequence command. Vcc power must remain HIGH to effectively register command.
19. Commands such as STORE and RECALL lock out I/O until operation is complete which further increases this time. See specific command.
