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