5.2 Exception Processing Registers

Cause Register (13)

The 32-bit read/write Cause register describes the cause of the most recent exception.

Figure 5-7 shows the fields of this register; Table 5-5 describes the Cause register fields. A 5-bit exception code (ExcCode) indicates one of the causes, as listed in Table 5-6.

All bits in the Cause register, with the exception of the IP(1:0) bits, are read-only; IP(1:0) are used for software interrupts.
