Notes
14. On a hardware STORE initiation, SRAM operation continues to be enabled for time tDELAY to allow READ/WRITE cycles to compete.
15. 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.
16. Commands like Store and Recall lock out I/O until operation is complete which further increases this time. See specific command.
