Functional Description - NXP Semiconductors freescale KV4 Series Reference Manual

Field
0 This peripheral does not require supervisor privilege level for accesses.
1 This peripheral requires supervisor privilege level for accesses.
5 Write Protect
WP6
Determines whether the peripheral allows write accesses. When this field 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 Trusted Protect
TP6
Determines whether the peripheral allows accesses from an untrusted master. When this field 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 This field is reserved.
Reserved This read-only field is reserved and always has the value 0.
2 Supervisor Protect
SP7
Determines whether the peripheral requires supervisor privilege level for accesses. When this field is set,
the master privilege level must indicate the supervisor access attribute, and the MPRx[MPLn] control field
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.
1 Write Protect
WP7
Determines whether the peripheral allows write accesses. When this field 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.
0 Trusted Protect
TP7
Determines whether the peripheral allows accesses from an untrusted master. When this field 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.
