23.4.3 ECC Status Register 1
Name: ECC_SR1
Access: Read-only
• RECERR0: Recoverable Error
0 = No Errors Detected.
1 = Errors Detected. If MUL_ERROR is 0, a single correctable error was detected. Otherwise multiple uncorrected errors
were detected.
• ECCERR0: ECC Error
0 = No Errors Detected.
1 = A single bit error occurred in the ECC bytes.
If TYPECORRECT = 0, read both ECC Parity 0 and ECC Parity 1 registers, the error occurred at the location which con-
tains a 1 in the least significant 16 bits; else read ECC Parity 0 register, the error occurred at the location which contains a
1 in the least significant 24 bits.
• MULERR0: Multiple Error
0 = No Multiple Errors Detected.
1 = Multiple Errors Detected.
• RECERR1: Recoverable Error in the page between the 256th and the 511th bytes or the 512th and the 1023rd
bytes
Fixed to 0 if TYPECORREC = 0.
0 = No Errors Detected.
1 = Errors Detected. If MUL_ERROR is 0, a single correctable error was detected. Otherwise multiple uncorrected errors
were detected.
• ECCERR1: ECC Error in the page between the 256th and the 511th bytes or the 512th and the 1023rd bytes
Fixed to 0 if TYPECORREC = 0
0 = No Errors Detected.
1 = A single bit error occurred in the ECC bytes.
Read ECC Parity 1 register, the error occurred at the location which contains a 1 in the least significant 24 bits.
• MULERR1: Multiple Error in the page between the 256th and the 511th bytes or the 512th and the 1023rd bytes
Fixed to 0 if TYPECORREC = 0.
0 = No Multiple Errors Detected.
1 = Multiple Errors Detected.
