(5) Sector Group Protection Algorithm
Setup Sector Group Addr.
(A19, A18, A17, A16, A15, A14, A13, A12)
Activate WE Pulse
WE = V IH, CE = OE = V IL
(A 9 should remain V ID
)
Yes
No
OE = VID, A9 = VID,
CE = VIL, RESET = VIH
A6 = A0 = VIL, A1 = VIH
PLSCNT = 1
Time out 100
s
Read from Sector Group
(Addr. = SPA, A1 = VIH,
A6 = V0 = VIL) *
Remove VID from A9
Write Reset Command
Increment PLSCNT
No
Yes
Protect Another Sector
Group ?
Data = 01h?
PLSCNT = 25?
Device Failed
Remove VID from A9
