9.3.2 Peripheral Access Control Register (AIPS_PACRn)
Each PACR register consists of eight 4-bit PACR fields. Each PACR field defines the
access levels for a particular on-platform peripheral. The peripheral assignment to each
PACR field is defined by the memory map slot of the peripheral. See the chip-specific
AIPS information for the field assignment of a particular peripheral.
Every PACR field to which no peripheral is assigned is reserved. Reads to reserved
locations return zeros, and writes are ignored.
The following table shows the location of each peripheral slot's PACR field in the PACR
registers.

AIPS_PACRn field descriptions
Field Description
31
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
30
SP0
Supervisor Protect
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 MPR
x [MPL n ] control field
for the master must be set. If not, access terminates with an error response and no peripheral access
initiates.
