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 you must assign to the controller depends on the number of
DMA channels used and whether you configure it to use the alternate channel control data structure.
See “Channel Configuration” on page 183 for details about the Channel Control Table. The base
address must be aligned on a 1024-byte boundary. You cannot read this register when the controller
is in the reset state.

Description
Channel Control Base Address
Pointer to the base address of the channel control table. The base
address must be 1024-byte aligned.
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.
