Section 4 Memory Management Unit (MMU)
4.2.2
The page table entry register low (PTEL) register residing at address H'FFFF FFF4, and used to
store the physical page number and page management information to be recorded in the TLB by
the LDTLB instruction. The contents of this register are only modified in response to a software
command.
4.2.3
The translation table base register (TTB) residing at address H'FFFF FFF8, which points to the
base address of the current page table. The hardware does not set any value in TTB automatically.
TTB is available to software for general purposes. The initial value is undefined.
