AIPSx_PACRn field descriptions (continued)
Field Description
Determines whether the peripheral requires supervisor privilege level for access. When this bit is set, the
master privilege level must indicate the supervisor access attribute , and the MPROTn[MPL] control bit for
the master must be set. If not, access terminates with an error response and no peripheral access
initiates.
0 This peripheral does not require supervisor privilege level for accesses.
1 This peripheral requires supervisor privilege level for accesses.
9
WP5
Write protect
Determines whether the peripheral allows write accesss. When this bit is set and a write access is
attempted, access terminates with an error response and no peripheral access initiates.
0 This peripheral allows write accesses.
1 This peripheral is write protected.
8
TP5
Trusted protect
Determines whether the peripheral allows accesses from an untrusted master. When this bit is set and an
access is attempted by an untrusted master, the access terminates with an error response and no
peripheral access initiates.
0 Accesses from an untrusted master are allowed.
1 Accesses from an untrusted master are not allowed.
7
Reserved
This read-only field is reserved and always has the value zero.
6
SP6
Supervisor protect
Determines whether the peripheral requires supervisor privilege level for access. When this bit is set, the
master privilege level must indicate the supervisor access attribute , and the MPROTn[MPL] control bit for
the master must be set. If not, access terminates with an error response and no peripheral access
initiates.
0 This peripheral does not require supervisor privilege level for accesses.
1 This peripheral requires supervisor privilege level for accesses.
5
WP6
Write protect
Determines whether the peripheral allows write accesss. When this bit is set and a write access is
attempted, access terminates with an error response and no peripheral access initiates.
0 This peripheral allows write accesses.
1 This peripheral is write protected.
4
TP6
Trusted protect
Determines whether the peripheral allows accesses from an untrusted master. When this bit is set and an
access is attempted by an untrusted master, the access terminates with an error response and no
peripheral access initiates .
0 Accesses from an untrusted master are allowed.
1 Accesses from an untrusted master are not allowed.
3
Reserved
This read-only field is reserved and always has the value zero.
