k: The six consecutive addresses must be in order listed. W must be high during all six consecutive cycles. See STORE cycle and RECALL
cycle tables and diagrams for further details.
The following six-address sequence is used for testing purposes and should not be used: 000, 555, 2AA, 7FF, 0F0, 39C.
l: Activation of nonvolatile cycles does not depend on the state of G.
m: I/O state assumes that G ≤ V_IL.
No.
