N = Nonvolatile

V = Volatile

Factory default

(binary)

Description

ASPO[15:6]

RESRVD

Reserved for Future

Use

N -> R/1

1111111111

This bit is Reserved for future use. This bit must always be

written/loaded to its default state.

ASPO[5]

ASPRDP

Read Password Based

Protection Selection

N -> R/1

Description: The ASPRDP bit selects the Read Password Mode

Protection mode. Read Password Protection mode works in

conjunction with Password Protection mode to protect all

sectors from Read/Erase/Program. Based on TBPROT configu-

ration bit (CFR1x[5]), either the top or bottom sector is available

for reading.

Selection Options:

0 = Read Password Protection Mode is enabled

1 = Read Password Protection Mode is disabled

Dependency: TBPROT (CFR1x[5])

ASPO[4]

ASPDYB

Dynamic Protection

(DYB) for all sectors at

power-up Selection

N -> R/1

Description: The ASPDYB bit selects whether all DYB bits

(sectors) are in the protected state following power-up or

hardware reset. DYB bits will individually need to be reset to

change sector protections.

Selection Options:

0 = DYB based sector protection enabled at power-up or

hardware reset

1 = DYB based sector protection disabled at power-up or

hardware reset

Dependency: N/A

ASPO[3]

ASPPPB

PermanentProtection

(PPB) bits for all

sectors programma-

bility Selection

N -> R/1

Description: The ASPPPB bit selects whether all PPB bits are

one-time programmable making PPB sector protection

permanent.

Note ASPPPB disables PPB erase transaction (ERPPB_0_0).

Selection Options:

0 = PPB bits are one-time programmable

1 = PPB bits can be erased and programmed as desired

Dependency: N/A

ASPO[2]

ASPPWD

Password Based

Protection Selection

N -> R/1

Description: The ASPPWD bit selects the Password Protection

Mode. Password Protection mode protects all PPB bits till the

correct password is entered. The ASPPWD can also be used in

combination with the ASPRDP to protect all registers and all

memory from erase/program and to protect sectors from being

read as well till the correct password is provided - except for top

or bottom sector which is available for reading based on

TBPROT configuration bit (CFR1x[5]).

Note When ASPPWD is selected, ASPO[15:0], CFR1N[7:2] and

PWDO[63:0] are protected against Write operations.

Selection Options:

0 = Password Protection Mode is enabled

1 = Password Protection Mode is disabled

Dependency: N/A

ASPO[1]

ASPPER

Persistent Protection

Selection (Register

Protection Selection)

N -> R/1

Description: The ASPPER bit selects the Persistent Protection

Mode. The Persistent Protection mode (ASPPER) protects the

ASPO[15:0], CFR1x[6, 5, 4, 2] and CFR3x[3] registers from erase

or program.

Selection Options:

0 = Persistent Protection Mode is enabled

1 = Persistent Protection Mode is disabled

Dependency: N/A

ASPO[0]

ASPPRM

PermanentProtection

Selection

N -> R/1

Description: The ASPPRM bit selects the Permanent Protection

Mode. The Permanent Protection mode (ASPPRM) permanently

protects the PPB bits from erase or program. ASPPRM bit should

be programmed once all the PPB based sector protections are

finalized.

Note Permanent protection is independent of the PPBLOCK bit.

Selection Options:

0 = Permanent Protection Mode is enabled

1 = Permanent Protection Mode is disabled

Dependency: N/A
