BUS OPERATION--1
Legend:
L=Logic LOW=VIL, H=Logic High=VIH, VID=12.0 0.5V, V HH=11.5-12.5V, X=Don't Care,
AIN=Address IN, DIN=Data IN,DOUT=Data OUT
Notes:
1. When the WP/ACC pin is at VHH, 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=VIL, the two outermost boot sectors remain protected. If WP/ACC=VIH, 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=VHH, 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=VIH), A20:A-1 in byte mode (BYTE=VIL).
