Register 6: DMA Channel Control Base Pointer (DMACTLBASE), offset 0x008
The DMACTLBASE register must be configured so that the base pointer points to a location in
system memory.
The amount of system memory that must be assigned to the μDMA controller depends on the
number of μDMA channels used and whether the alternate channel control data structure is used.
See “Channel Configuration” on page 683 for details about the Channel Control Table. The base
address must be aligned on a 1024-byte boundary. This register cannot be read when the μDMA
controller is in the reset state.

Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
