For products processed in the T7Y process only (see
Important note
):
Protection always prevails:
When the Lock Down Bit of Sector 0 or Sector 15 is set to ‘1’.
–
If the Lock Down Bit of Sector 0 is ‘1’, all the Lock Down Bits of the subsectors in
Sector 0 are forced to ‘1’.
–
If the Lock Down Bit of Sector 15 is ‘1’, all the Lock Down Bits of the subsectors in
Sector 15 are forced to ‘1’
When the Write Lock Bit of Sector 0 or Sector 15 is set to ‘1’.
–
if the Write Lock Bit of Sector 0 is ‘1’, the Write Lock Bits of all the subsectors in
Sector 0 are forced to ‘1’ (even if their Lock Down Bits are set to ‘1’).
–
if the Write Lock Bit of Sector 15 is ‘1’, the Write Lock Bits of all the subsectors in
Sector 15 are forced to ‘1’ (even if their Lock Down Bits are set to ‘1’).
When the Write Lock Bit of Sector 0 or Sector 15 is reset to ‘0’.
–
if the Write Lock Bit of Sector 0 is ‘0’, all the subsectors in Sector 0 whose Lock
Down Bit is ‘0’ have their Write Lock Bits forced to ‘0’.
–
if the Write Lock Bit of Sector 15 is ‘0’, all the subsectors in Sector 15 whose Lock
Down Bit is ‘0’ have their Write Lock Bits forced to ‘0’.
When the Write Lock Bit of any sector or subsector is set to ‘1’, any instruction that may
modify the contents of this sector or subsector will be rejected (including Sector Erase
and Bulk Erase).

Note that when the WRLR instruction acts both on Write Lock (WL) and Lock Down (LD)
bits, it firstly programs the WL bit, and then the LD bit.
As an example, if a subsector Lock Register settings are xxxx0101b and a WRLR instruction
is issued with a Lock Register In data set to 00000010b:
1.
the sector WL bit is first set to ‘0’ (and all subsectors that are not locked-down will have
their WL bit reset to ‘0’).
2.
the sector LD bit and all subsectors LD bits are set to ‘1’. In this case, the final value of
the above subsector Lock Register is xxxx1010b.
