4.5.6 MPU access permission attributes
This section describes the MPU access permission attributes. The access permission bits, TEX, C, B,
S, AP, and XN, of the RASR, control access to the corresponding memory region. If an access is made
to an area of memory without the required permissions, then the MPU generates a permission fault.
Table 4.45 (p. 119) shows the encodings for the TEX, C, B, and S access permission bits.

2See Table 4.46 (p. 119) for the encoding of the AA and BB bits.
Table 4.46 (p. 119) shows the cache policy for memory attribute encodings with a TEX value is in
the range 4-7.
