Configuration protection

ASP provides provisions to protect device's configuration through Persistent Protection scheme. Selecting bit 1

in Advanced Sector Protection Register (ASPO[1] - ASPPER) selects the Persistent Protection scheme and protects

the following registers or register bits from write or program.

• CFR1V[6,5,4,2]/CFR1N[6,5,4,2] - SP4KBS, TBPROT, PLPROT, TB4KBS

• CFR3N[3]/CFR3V[3] - UNHYSA

• ASPO[15:0]

• PWDO[63:0]

The Persistent Protection scheme flowchart is shown in Figure 46.
