Nonvolatile Recall
Note p: 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 q: While there are 18 addresses on the STK14EC16, only the lower 16 are used to control software modes
Note r: I/O state depends on the state of G, UB, and LB. The I/O table shown assumes G, UB, and LB low.
