PUMA 68F32006/A-90/12/15
Issue 4.2 : December 1999
Sector Group Protection
The device features hardware sector group protection. This feature will disable both program and erase
operations in any combination of sector groups of memory. The sector protect feature is enabled using pro-
gramming equipment at the users site. The device is shipped with all sector groups unprotected.
It is also possible to determine if a sector is protected in the system by writing the autoselect command.
Performing a read operation at XX02H , where the higher order addresses (A17, A18, A19) is the desired
sector group address, will produce 01H data at DQ0 for a protected sector group.
