Hardware Property Area on U2x devices consists of seven areas, but the focus
here is on the following four:
- Configuration Setting Area (CSA)
- Security Setting Area (SSA)
- Block protection area 0 (BPA0)
- Block protection area 1 (BPA1 is not available on smaller devices)
Each of these areas is further divided into 2 areas (Area 0 and Area 1)
that can be mapped to the front or back side address range:
-
Front side - Contains valid area which cannot be updated
(programmed)
-
Back side - Contains invalid area which can be programmed with new
settings.
