In-System Sector Protect/Unprotect Algorithms
Sector Protect:
Write 60h to sector
address with
A6 = 0, A1 = 1,
A0 = 0
Set up sector
address
Wait 150 s
Verify Sector
Protect: Write 40h
to sector address
with A6 = 0,
A1 = 1, A0 = 0
Read from
sector address
with A6 = 0,
A1 = 1, A0 = 0
START
PLSCNT = 1
RESET# = VID
Wait 1
s
First Write
Cycle = 60h?
Data = 01h?
Remove VID
from RESET#
Write reset
command
Sector Protect
complete
Yes
No
PLSCNT

Yes
Device failed
Increment
PLSCNT
Temporary Sector
Unprotect Mode
No
Sector Unprotect:
Write 60h to sector
address with
A6 = 1, A1 = 1,
A0 = 0
Set up first sector
address
Wait 15 ms
Verify Sector
Unprotect: Write
40h to sector
address with
A6 = 1, A1 = 1,
A0 = 0
Read from
sector address
with A6 = 1,
A1 = 1, A0 = 0

Yes
Protect all sectors:
The indicated portion
of the sector protect
algorithm must be
performed for all
unprotected sectors
prior to issuing the
first sector
