The FSR accessed is determined by the value of the Opcode_2 field:
Opcode_2 = 0
Opcode_2 = 1
The fault type encoding is listed in Table 3-9 on page 3-22.
You can access the FSRs using the following instructions:
The format of the Fault Status Register is shown in Figure 2-8.
Table 2-15 shows the bit field descriptions for the FSR.
