4.5.2

Advanced sector protection (ASP)

The advanced sector protection scheme allows each memory array sector to be independently controlled for

protection against erasing or programming, either by volatile or nonvolatile locking features. The nonvolatile

locking configuration can also be locked, as well as password-protected.

The main memory array sectors are protected against erase and program by volatile (DYB) and nonvolatile (PPB)

protection bit pairs. Each DYB/PPB bit pair can be individually set to '0' protecting the related sector or cleared

to '1' unprotecting the related sector. DYB protection bits can be set and cleared as often as needed whereas PPB

bits being nonvolatile must adhere to their respective technology based endurance requirements. Figure 44

shows an overview of ASP.
