Nonvolatile Recall
Note k: 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 l: While there are 17 addresses on the STK16CA8, only the lower 16 are used to control software modes.
Note m: I/O state depends on the state of G. The I/O table shown assumes G low.
