11.7.11
Access: Read/Write
The CP15 Register 10, or TLB Lockdown Register, is 0x0 on reset. There is a TLSB Lockdown Register for each of the
TLBs; the value of opcode_2 determines which TLB register to access:
Table 11-9.
• Base[31:26]: Base
The TLB replacement strategy only uses the TLB entries numbered from base to 63. The Victim field provided is in that
range.
• Victim[25:20]: Victim Counter
Specifies the TLB entry (line) being overwritten.
• P[0]: Preserved
If 0, the TLB entry can be invalidated.
If 1, the TLB entry is protected. It cannot be invalidated during the Invalidate All instruction. Refer to
Operations Register” on page
The non-defined bits should be zero when written and are unpredictable when read.
11.7.12
Any access (Read or Write) to these registers causes unpredictable behavior.
