Description added
The TLB uses a 4-way set associative scheme, so entries must be
selected by index. VPN bits 16 to 12 and ASID bits in PTEH 4 to 0
are used as the index number regardless of the page size. …
Description added
Software (TLB Protection Violation Handler) Operations: Software
resolves the TLB protection violation and issues the RTE (return from
exception handler) instruction to terminate the handler and return to
the instruction stream. Note that the RTE instruction should be
issued after the two instructions following the LDTLB instruction.
Description deleted
Invalidating Specific Entries: Specific TLB entries can be invalidated
by writing 0 to the entry's V bit. R0 specifies the write data and R1
specifies the address.
Bit 5 R/W amended
(Before) R → (After) R/W
Note amended
Note: For logical address spaces P0 and P3, when the memory
management unit (MMU) is on, it can optionally generate a
physical address for the logical address. It can be applied when
the MMU is off and when the MMU is on and each physical
address for the logical address is equal except for upper three
bits. See table 8.2, Physical Address Space Map, for
information on converting logical addresses into user-defined
physical addresses.

… The number of bus cycles is selected between 0 and 10 wait
cycles using the A0W2 to A0W0 bits of WCR2. In addition, any
number of waits can be inserted in each bus cycle by means of the
external wait pin (WAIT). When the burst function is used, the bus
cycle pitch of the burst cycle is determined within a range of 2 to 10
according to the number of waits.
