In the PBRIDGE_A_PACR0 and PBRIDGE_B_PACR0 registers, the BW0 bit is not writeable
2
The default values are always used for the SP0 and TP0 bits, even though the bits are writeable.

BWn
Buffer writes. Determines whether write accesses to this peripheral are allowed to be buffered. Write
accesses not bufferable by default
0 No write accesses are bufferable by the PBRIDGE to this peripheral.
1 Write accesses can be buffered by the PBRIDGE to this peripheral.
Note: In PBRIDGE_A_PACR0 and PBRIDGE_B_PACR0, the BW0 bit is not writeable.

SPn
Supervisor protect. Determines whether the peripheral requires supervisor privilege level for access.
Supervisor privilege level required by default.
0 The peripheral does not require supervisor privilege level for accesses.
1 The peripheral requires supervisor privilege level for accesses.
The PBRIDGE_x_MPCR[MPLy] control bit for the master must be set. If not, access is terminated
with an error response and no peripheral access is initiated on the slave bus.
Note: For PBRIDGE_A_PACR0 and PBRIDGE_B_PACR0, you must have supervisor privileges to
access PBRIDGE registers.
Note: Even though the SP0 bit (1) is writeable, the reset value for SP0 is always used.
