12-2 Freescale Semiconductor
• System access control unit (SACU) programming model
— Master privilege register (MPR)
— Peripheral access control registers (PACRs)
— Grouped peripheral access control registers (GPACR0, GPACR1)
12.4 Memory Map and Register Definition
The memory map for the SCM registers is shown in Table 12-1 . All the registers in the SCM are
memory-mapped as offsets within the 1-Gbyte IPS address space and accesses are controlled to these
registers by the control definitions programmed into the SACU.
