Nonvolatile Recall
Notes
i: The six consecutive addresses must be in the order listed.
j: While there are 17 addresses on the STK14CA8, only the lower 16 are used to control software modes
W
must be high during all six consecutive cycles to enable a nonvolatile cycle.
k: I/O state depends on the state of
G
. The I/O table shown assumes
G
low.
