11.7.3
Access: Read/Write
The CP15 Register 2, or Translation Table Base (TTB) Register, defines the first-level translation table.
• Pointer[31:14]
Points to the first-level translation table base. Read returns the currently active first-level translation table. Write sets the
pointer to the first-level table to the written value.
The non-defined bits should be zero when written and are unpredictable when read.
