MPC8308 PowerQUICC II Pro Processor Reference Manual, Rev. 1

3-2 Freescale Semiconductor

In certain specific cases, reserved bits should not be cleared but should keep their reset value. Thus, the

software should perform a ‘read-modify-write’ and make sure that it does not change the reset value of

those bits. The description of the specific bits indicate when this is needed.

Cross-references are provided to the IMMRBAR maps for each individual block. A complete listing of all

registers is provided in Appendix A, “Complete List of Configuration, Control, and Status Registers.”
