Nonvolatile RECALL  
Note l: The six consecutive addresses must be in the order listed. W must be high during all six consecutive E controlled cycles to enable a nonvola-  
tile cycle.  
Note m: While there are 15 addresses on the STK15C88, only the lower 14 are used to control software modes.

Note n: The software sequence is clocked on the falling edge of E controlled READs without involving G (double clocking will abort the sequence).  
See application note: MA0002 http://www.simtek.com/attachments/AppNote02.pdf.  
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.
