Document Control #ML0012 Rev 0.3

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 STK11C88, only the lower 14 are used to control software modes.

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.
