Notes

15. t

HRECALL

starts from the time V

rises above V

SWITCH

16. CE

and OE low and WE high for output behavior.

17. HSB

is asserted low for 1us when V

CAP

drops through V

SWITCH

. If an SRAM WRITE has not taken place since the last nonvolatile cycle, HSB will be released and no

store will take place.
