Features

4.1.1.2

ECC error address trap (EATV)

• A 32-bit register is provided to capture the ECC data unit address where an ECC error is first encountered during

a read of the flash array. Only the address of the first enabled error type (“2-bit only” or “1-bit or 2-bit” as selected

in CFR2x[6]) encountered after POR, hardware reset, or the ECC Clear transaction is captured. The EATV Register

is only updated during Read transactions.

The EATV Register contains the address that was accessed when the error was detected. The failing bits may

not be located at the exact address indicated in the register, but will be located within the aligned 16-byte ECC

data unit where the error was detected. If errors are found in multiple ECC data units during a single read

operation, only the address of the first failing ECC unit address is captured in the EATV Register.

When 2-bit error detection is not enabled and the same ECC unit is programmed more than once, ECC error

detection for that ECC unit is disabled, therefore no error is recognized to trap the address.

• The Address Trap Register can be read using HYPERBUS™ or Legacy (x1) SPI Address Trap Register read trans-

action.

• Clear ECC Status Register transaction, POR, or CS# Signaling/Hardware/Software reset clears the Address Trap
