Base Address
Register
Provides the offset to which all register space for MPC5200B is accessed. The reset value
of this register is 0x8000, which provides for a MBAR of 0x8000 0000. All of MPC5200B
registers are then accessible at MBAR+offset, where offset refers to the given value in
of this register is 0x8000, which provides for a MBAR of 0x8000 0000. All of MPC5200B
registers are then accessible at MBAR+offset, where offset refers to the given value in
for the respective module.
