HARDWARE MODE SELECTION
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,
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
HARDWARE STORE CYCLE
Note p: E and G low for output behavior.
Note q: E and G low and W high for output behavior.
Note r:
