3.6.2 Address translation
Virtual addresses are translated into physical addresses by the internal TLB (Translation Lookaside Buffer) in page
units. The TLB has a full-associative configuration and has 64 entries at the virtual address side and 32 entries at the
physical address side. The page size is variable from 1 K to 256 Kbytes.
If a TLB entry is not found, a TLB non-coincidence exception occurs in the 32-bit mode, and an XTLB non-coincidence
exception occurs in the 64-bit mode. Change the contents of the TLB in software.
The following figure outlines address translation.
