Address register (BadVAddr) is a read-only register that displays the most recent virtual address that caused either a TLB or Address Error exception. The BadVAddr register remains unchanged during Soft Reset, NMI, or Cache Error exceptions. Otherwise, the architecture leaves this register undefined.
Figure 14-8 shows the format of the BadVAddr register.
