5.2 Exception Processing Registers

Error Exception Program Counter (Error EPC) Register (30)


The ErrorEPC register is similar to the EPC register, except that ErrorEPC is used on ECC and parity error exceptions. It is also used to store the program counter (PC) on Reset, Soft Reset, and nonmaskable interrupt (NMI) exceptions.

The read/write ErrorEPC register contains the virtual address at which instruction processing can resume after servicing an error. This address can be:

There is no branch delay slot indication for the ErrorEPC register.

Figure 5-13 shows the format of the ErrorEPC register.
