Soft Sequence Commands
Notes:
o: 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 com-
mand.
p: Commands like Store and Recall lock out I/O until operation is complete which further increases this time. See specific command.
