SOFTWARE STORE/RECALL MODE SELECTION
SOFTWARE-CONTROLLED STORE/RECALL CYCLEv
(VCC = 5.0V ± 10%)e
Note r:
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 s: While there are 15 addresses on the STK14C88, only the lower 14 are used to control software modes.
Note t:
I/O state assumes G < VIL. Activation of nonvolatile cycles does not depend on state of G.
Note u: The software sequence is clocked with E controlled READs.
Note v: The six consecutive addresses must be in the order listed in the Hardware Mode Selection Table: (0E38, 31C7, 03E0, 3C1F, 303F, 0FC0) for
a STORE cycle or (0E38, 31C7, 03E0, 3C1F, 303F, 0C63) for a RECALL cycle. W must be high during all six consecutive cycles.
