Registers

5.2.6

ECC error detection count register (ECTV) (x8)

The ECC Error Detection Count Register (ECTV) stores the number of either 1-Bit/2-Bit or only 1-Bit ECC errors

have occurred during read operations since the last POR or hardware/software reset.

5.2.7

ASP password register (PWDO) (x8)

The ASP Password Register (PWDO) is used to permanently define a password.

Description

ECTV[15:0]

ECCCNT[15:0]

ECC 1-bit and 2-bit Error

Count Register

V => R

0x0000

Description: The ECCCNT[15:0] stores the number of

1-bit/2-bit ECC errors occurred during read operations

since the last POR or hardware/software reset.

Note ECCCNT[15:0] is only updated during Read

Instruction.

Note Only one ECC error is counted for each data unit. If

multiple read transactions access the same unit data

containing an ECC error, the ECCCNT[15:0] will

increment each time the unit data is read.

Note Once the count reaches 0xFFFF, the ECCCNT[15:0]

will stop incrementing

Note POR or Hardware/Software reset clears the

ECCNT[15:0] to 0x0000.

Selection Options: ECC Error Count
