Nonvolatile Recall
Notes
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.
r: While there are 17 addresses on the STK14CA8, only the lower 16 are used to control software modes
s: I/O state depends on the state of G. The I/O table shown assumes G low
