Section 3 Memory Management Unit (MMU)
3.6
In order for TLB operations to be managed by software, TLB contents can be read or written to in
the privileged mode using the MOV instruction. The TLB is assigned to the P4 area in the logical
address space. The TLB address array (VPN, V bit, and ASID) is assigned to H'F2000000 to
H'F2FFFFFF, and the data array (PPN, PR, SZ, C, D, and SH bits) to H'F3000000 to
H'F3FFFFFF. The V bit in the address array can also be accessed from the data array. Only
longword access is possible for both the address array and the data array.
