Registers

5.2.15

Memory array data integrity check CRC register (DCRV) (x8)

The Memory Array Data Integrity Check CRC Register (DCRV) stores the results of the CRC calculation on the data

contained between the specified starting and ending addresses.

5.2.16

Interface CRC check-value register (ICRV) (x8)

The Interface CRC Check-value Register (ICRV) stores the results of the CRC calculation on the command and Data

Content over the interface for Protection.

SECV[23]

SECCPT

Sector Erase Count

Corruption Status Flag

V => R

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

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

times a sector has been erased.

Selection Options: Value

Dependency: N/A

0xFFFFFFFF

Description: The DTCRCV[31:0 bits store the checksum

value of the CRC process on the memory array data

contained within the starting address and the ending

address.
