When writing, the write is performed to the entry selected with the index address and way.
When reading, the VPN, V bit, and ASID of the entry selected with the index address and way in
the format of the data field in figure 3.12 without comparing addresses. 0 is written to data field
bits 16–12.
To invalidate a specific entry, specify the entry and way, and write 0 to the corresponding V bit.
3.6.2
Data Array
The data array is assigned to H'F3000000–H'F3FFFFFF. To access a data array, the 32-bit address
field (for read/write operations), and 32-bit data field (for write operations) must be specified. The
address section specifies information for selecting the entry to be accessed; the data section
specifies the longword data to be written to the data array (figure 3.15 (2)). Longword data has the
same bit configuration as PTEL.
In the address field, specify VPN (16–12) as the index address for selecting the entry (bits 16–12),
the W bits for selecting the way (bits 9–8), and H'F3 to indicate data array access (bits 31–24).
The IX bit in MMUCR indicates whether the EX-OR of VPN (16–12) and ASID (4–0) in the
PTEH register is used as the index address.
Both reading and writing use longword data of the data array specified by the entry address and
way number.
