HID1[RFXE]). If RFXE is zero and this error occurs, ERR_DISABLE[MBED] and
ERR_INT_EN[MBEE] must be zero and ECC_EN must be one to ensure an interrupt is generated.
See
e500 Core Family Reference Manual for further details.
0 No ECC errors are reported. No ECC interrupts are generated.
1 ECC is enabled.
0 Indicates unbuffered DIMMs.
1 Indicates registered DIMMs.
