Each interrupt has an associated interrupt vector address, obtained by concatenating the IVPR value with
the address index in the associated IVOR (that is, IVPR[32–47] || IVORn[48–59] || 0b0000). The resulting
address is that of the instruction to be executed when that interrupt occurs. IVPR and IVOR values are
indeterminate on reset, and must be initialized by the system software using mtspr.

Machine check address register—Holds the address of the data or instruction that caused the machine check
interrupt. MCAR contents are not meaningful if a signal triggered the machine check interrupt.
Machine check syndrome register—Holds machine state information on machine check interrupts and restores
machine state after an rfmci instruction is executed.
Exception syndrome register—Provides a syndrome to differentiate between the different kinds of exceptions that
generate the same interrupt type. Upon generation of a specific exception type, the associated bit is set and all
other bits are cleared.
as well as various condition bits associated with the operations performed by the SPE.
Data exception address register—Holds the address that was referenced by a load, store, or cache management
instruction that caused an alignment, data TLB miss, or data storage interrupt.
Together, IVPR[32–47] || IVOR n [48–59] || 0b0000 define the address of an interrupt-processing routine. See
