Nonvolatile Recall
Note q: 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 r: While there are 19 addresses on the STK14EC8, only the lower 16 are used to control software modes
Note s: I/O state depends on the state of G. The I/O table shown assumes G low
