Example 2: Internal Request Generation, Memory to Memory Transfers.
***************************************************************************
* MC68340 basic DMA channel register initialization example code.
* This code is used to initialize the 68340's internal DMA channel
* registers, providing basic functions for operation.
* The code sets up channel 1 for internal request generation
* memory to memory transfers.
