DMA Controller Registers
10.3.4 DMA Destination Address Register (DDAR)
The DDAR provides a 32-bit address that the DMA controller drives onto the internal
address bus for all of the channel’s write accesses. The address is altered after each write
access according to the addressing mode.
10.3.5 DMA Byte Count Register (DBCR)
The DBCR is initially loaded with the number of bytes to be transferred during the DMA.
After each transfer, the DBCR decrements by the number of bytes transferred. DIR[ASC]
is set when the byte counter reaches zero. The user must ensure that the bytes remaining to
be transferred and the transfer size are such that the byte counter decrements to zero or
wraps around without setting the ASC flag.
