Registers

5.3.19

Sector erase count register (SECV) (x1)

The Sector Erase Count Register (SECV) contains the number of times the addressed sector has been erased.

5.3.20

Infineon Endurance Flex architecture selection register (EFXx) (x1)

The Infineon Endurance Flex architecture selection registers (EFXx) define the long retention / high

endurance regions based on a four pointer based architecture.

default

(hex)

Description

SECV[23]

SECCPT

Sector Erase Count

Corruption Status Flag

V -> R

0x0

Description: The SECCPT bit is used to determine if the

reported sector erase count is corrupted and was reset.

Note If SECCPT is set due to count corruption, it will

reset to 0 on the next successful erase operation on the

selected sector.

Selection Options:

0 = Sector Erase Count is not corrupted and is valid

1 = Sector Erase Count is corrupted and is not valid

Dependency: N/A

SECV[22:0]

SECVAL[22:0] Sector Erase Count Value

V -> R

0x000000

Description: The SECVAL[22:0] bits store the number of

times a sector has been erased

Selection Options: Value

Dependency: N/A
