GBLSEL

All Sectors based

Region type Selection

N => R/1

Description: The GBLSEL bit defines whether all sectors

are defined as long retention region or high endurance

region.

Note If all other Pointer registers are disabled, this bit

defines the behavior of the entire memory space and is

hardwired to start at Sector 0.

Selection Options:

0 = Long Retention Sectors

1 = High Endurance Sectors

Dependency: N/A

EFX0O[0]

WRLVEN

Wear Leveling Enable

Selection

N => R/1

Description: The WRLVEN bit enables/disables the wear

leveling feature.

Selection Options:

0 = Wear Leveling Disabled

1 = Wear Leveling Enabled

Dependency: N/A
