SOFTWARE STORE/RECALL MODE SELECTION
Note l:
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 m: While there are 15 addresses on the STK16C88-3, only the lower 14 are used to control software modes.
SOFTWARE STORE/RECALL CYCLEn, o
(VCC = 3.0V-3.6V)
Note n:
The software sequence is clocked with E controlled reads.
Note o:
The six consecutive addresses must be in the order listed in the Software STORE/RECALL 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.
