DMA Controller
10.3.4
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
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.
