Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 8.5 ~ 12.5 V, VHH = 9.0 ± 0.5 V, X = Don’t Care, SA = Sector
Address, AIN = Address In, DIN = Data In, DOUT = Data Out.
Notes:
1.
Addresses are A20:A0 in word mode (#BYTE = VIH), A20: A-1 in byte mode (#BYTE = VIL).
2.
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 Unprotect ion”. If #WP/ACC = VHH, all sectors will be unprotected.
