Field
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.

19.4 Functional description

The peripheral bridge functions as a bus protocol translator between the crossbar switch
and the slave peripheral bus.
The peripheral bridge manages all transactions destined for the attached slave devices and
generates select signals for modules on the peripheral bus by decoding accesses within
the attached address space.

19.4.1 Access support

All combinations of access size and peripheral data port width are supported. An access
that is larger than the target peripheral's data width will be decomposed to multiple,
smaller accesses. Bus decomposition is terminated by a transfer error caused by an access
to an empty register area.
