19.9.3 Uncorrectable Error Address Register (UERRADDR)
The uncorrectable error address register gives the address of the first uncorrectable error location.
NOTE: No computation is needed when reading the complete register to retrieve the address in the
Interrupt Vector Table.
This register will never be reset by a power-on reset nor any other reset source.

offset
Interrupt Vector Table offset. Reads are always FFF8 2xxxh; writes have no effect.
9-2 ADDERR Uncorrectable error address register. This register gives the address of the first encountered double-bit
error since the flag has been clear. Subsequent ECC errors will not update this register until the UERR
flag has been cleared.
Note: This register is valid only when PARFLG is set (see Section 19.9.1).
1-0 Word offset Word offset. Reads are always 0; writes have no effect.
19.9.4 Fallback Vector Address Register (FBVECADDR)
This register provides a fall-back address to the VIM if a uncorrectable error has occurred in the Interrupt
Vector Table. Figure 19-15 and Table 19-9 describe this register.
NOTE: This register will never be reset by a power-on reset nor any other reset source.

Table 19-9. Fallback Vector Address Register (FBVECADDR) Field Descriptions
Bit Field Description
31-0 FBVECADDR Fallback Vector Address Register. This register is used by the VIM if the Interrupt Vector Table has been
corrupted. The contents of the IRQVECREG and FIQVECREG registers will reflect the value programmed
in FBVECADDR. The value provided to the VIC port will also reflect FBVECADDR until the UERR register
has been cleared.
This register provides the address of the ISR that will restore the integrity of the Interrupt Vector Table.
