Notes:
1. When the WP/ACC pin is at V
, the device enters the accelerated program mode. See "Accelerated Program
Operations" for more information.
2.The sector group protect and chip unprotect functions may also be implemented via programming equipment. See
the "Sector Group Protection and Chip Unprotection" section.
3.If WP/ACC=V
, the two outermost boot sectors remain protected. If WP/ACC=V
, the two outermost boot sector
protection depends on whether they were last protected or unprotected using the method described in "Sector/
Sector Block Protection and Unprotection". If WP/ACC=V
, all sectors will be unprotected.
4.DIN or Dout as required by command sequence, data polling, or sector protection algorithm.
5.Address are A20:A0 in word mode (BYTE=V
IH
), A20:A-1 in byte mode (BYTE=V
IL
).
