Peripheral Bridge (PBRIDGE A and PBRIDGE B)MPC5566 Microcontroller Reference Manual, Rev. 25-4 Freescale Semiconductor5.2 External Signal DescriptionThe PBRIDGE has no external signals.5.3 Memory Map and Register DefinitionsThe memory map for the 32-bit PBRIDGE A registers is shown in Table 5-2.The memory map for the 32-bit PBRIDGE B registers is shown Table 5-3.5.3.1 Register DescriptionsThere are three types of registers that control each PBRIDGE. All registers are 32-bit registers and mustbe accessed in supervisor mode by trusted bus masters. Additionally, these registers must only be readfrom or written to by a 32-bit aligned access. PBRIDGE registers are mapped into the PBRIDGE A andTable 5-2.
