Nonvolatile RECALL

Note m: HSB STORE operation occurs only if an SRAM WRITE has been done since the last nonvolatile cycle. After the STORE (if any) completes,

the part will go into standby mode, inhibiting all operations until HSB rises.

Note n: The six consecutive addresses must be in the order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle.

Note o: I/O state assumes G < V_IL. Activation of nonvolatile cycles does not depend on state of G.
