14.1 Index Register (0)

The Index register is a 32-bit, read/write register containing six bits to index an entry in the TLB. The high-order bit of the register shows the success or failure of a TLB Probe (TLBP) instruction.

The Index register also specifies the TLB entry affected by TLB Read (TLBR) or TLB Write Index (TLBWI) instructions.

Figure 14-1 shows the format of the Index register; Table 14-2 describes the Index register fields.
