Notes

18.On a hardware STORE initiation, SRAM operation continues to be enabled for time tDELAY to allow read and write cycles to complete.

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

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