Reserved, should be cleared.
Entry select. Number of entry in selected array to be used for tlbwe. This field is also updated on TLB
error exceptions (misses), and tlbsx hit and miss cases. Only certain bits are valid, depending on the array
selected in TLBSEL. Other bits should be 0.
For the e500, ESEL serves as the way select for the corresponding TLB as follows:
When TLBSEL = 00 (TLB0 selected), bits 46–47 are used (and bits 44–45 should be cleared). This field
selects between way 0, 1, 2, or 3 of TLB0. EA bits 45–51 from MAS2[EPN] are used to index into the TLB
to further select the entry for the operation. Note that for the e500v1, bit 47 selects either way 0 or way 1,
and bit 46 should remain cleared.
When TLBSEL = 01 (TLB1 selected), all four bits are used to select one of 16 entries in the array.
Reserved, should be cleared.
Next victim. Next victim bit value to be written to TLB0[NV] on execution of tlbwe. This field is also updated
on TLB error exceptions (misses), tlbsx hit and miss cases and on execution of tlbre.
This field is updated based on the calculated next victim bit for TLB0 (based on the round-robin
replacement algorithm.)
Note that this field is not defined for operations that specify TLB1 (when TLBSEL = 01).
