1
In PBRIDGE_A_PACR0 and in PBRIDGE_B_PACR0, the BW0 bit is not writable.
2
The default value is 0b0000 for PACR peripheral access fields that are unused or not connected.

1
Buffer writes. Determines whether write accesses to this peripheral are allowed to
be buffered. Write accesses not bufferable by default
0 Write accesses to this peripheral are not bufferable by the PBRIDGE.
1 Write accesses to this peripheral are allowed to be buffered by the PBRIDGE.
Note: In PBRIDGE_A_PACR0 and PBRIDGE_B_PACR0, the BW0 bit is not
writable.

SPn
Supervisor protect. Determines whether the peripheral requires supervisor
privilege level for access. Supervisor privilege level required by default.
0 This peripheral does not require supervisor privilege level for accesses.
1 This peripheral requires supervisor privilege level for accesses. The
PBRIDGE_x_MPCR[MPLy] control bit for the master must be set. If not, the
access is terminated with an error response and no peripheral access is
initiated on the slave bus.
