8 | * This file contains structures and information for the communication |
9 | * processor channels. Some CPM control and status is available | |
10 | * throught the MPC8xx internal memory map. See immap.h for details. | |
11 | * This file only contains what I need for the moment, not the total | |
12 | * CPM capabilities. I (or someone else) will add definitions as they | |
13 | * are needed. -- Dan | |
