Note:
6.2.1
PTEH can be accessed in longwords from H'FF00 0000 in the P4 area and from H'1F00 0000 in
area 7. PTEH consists of the virtual page number (VPN) and address space identifier (ASID).
When an MMU exception or address error exception occurs, the VPN of the virtual address at
which the exception occurred is set in the VPN bit by hardware. VPN varies according to the page
size, but the VPN set by hardware when an exception occurs consists of the upper 22 bits of the
virtual address which caused the exception. VPN setting can also be carried out by software. The
number of the currently executing process is set in the ASID bit by software. ASID is not updated
by hardware. VPN and ASID are recorded in the UTLB by means of the LDLTB instruction.
After the ASID field in PTEH has been rewritten, a branch instruction to the P0, P3, or U0 area
that uses the updated ASID value should be located at least six instructions after the PTEH update
instruction.
