- * This file only contains what I need for the moment, not the total
- * CPM capabilities. I (or someone else) will add definitions as they

- * On the MBX board, EPPC-Bug loads CPM microcode into the first 512
- * bytes of the DP RAM and relocates the I2C parameter area to the
- * IDMA1 space. The remaining DP RAM is available for buffer descriptors
