15.t
HRECALL
starts from the time V
CC
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.
