The Data Polling Status word appears at all word locations in the device address space. When an EA is
completed the Data Polling Status ASO is exited and the device address space returns to the address map
mode where the EA was started.
Note that in future technology nodes the Data Polling Status feature will not be supported. The user is
strongly advised to use the Status Register to determine device status.
The Secure Silicon Region (SSR) provides an extra flash memory area that can be programmed once and
permanently protected from further changes i. e. it is a One Time Program (OTP) area. The SSR is 1024-
bytes in length. It consists of 512-bytes for Factory Locked Secure Silicon Region and 512-bytes for
Customer Locked Secure Silicon Region.
The sector address supplied during the Secure Silicon Entry command selects the Flash Memory Array
sector that is overlaid by the Secure Silicon Region address map. The SSR is overlaid starting at location 0 in
the selected sector. Use of the sector 0 address is recommended for future compatibility. While the SSR ASO
is entered the content of all other sectors is undefined. Locations above the maximum defined address of the
SSR ASO to the maximum address of the selected sector have undefined data.
The Lock register ASO contains a single word of OTP memory. When the ASO is entered the Lock Register
appears at all word locations in the device address space. However, it is recommended to read or program
the Lock Register only at location 0 of the device address space for future compatibility.
The PPB ASO contains one bit of a Flash Memory Array for each Sector in the device. When the PPB ASO is
entered, the PPB bit for a sector appears in the Least Significant Bit (LSB) of each word in the sector.
Reading any word in a sector displays a word where the LSB indicates the non-volatile protection status for
that sector. However, it is recommended to read or program the PPB only at word location 0 of the sector for
future compatibility. If the bit is 0 the sector is protected against programming and erase operations. If the bit
is 1 the sector is not protected by the PPB. The sector may be protected by other features of ASP.
The PPB Lock ASO contains a single bit of volatile memory. The bit controls whether the bits in the PPB ASO
may be programmed or erased. If the bit is 0 the PPB ASO is protected against programming and erase
operations. If the bit is 1 the PPB ASO is not protected. When the PPB Lock ASO is entered the PPB Lock bit
appears in the Least Significant Bit (LSB) of each word in the device address space. However, it is
recommended to read or program the PPB Lock only at word location 0 of the device for future compatibility.
The Password ASO contains four words of OTP memory. When the ASO is entered the Password appears
starting at address 0 in the device address space. All locations above the forth word are undefined.
