Note l: The six consecutive addresses must be in order listed. W must be high during all six consecutive cycles to enable a nonvolatile cycle.
Note m: While there are 15 addresses on the STK11C88-3, only the lower 14 are used to control software modes.

The six consecutive addresses must be in the order listed in the Software STORE/RECALL Mode Selection Table: (0E38, 31C7, 03E0, 3C1F,
303F, 0FC0) for a STORE cycle or (0E38, 31C7, 03E0, 3C1F, 303F, 0C63) for a RECALL cycle. W must be high during all six consecutive
cycles.
