6.7 REGISTER DESCRIPTION
The following paragraphs contain a detailed description of each register and its specific
function. Figure 6-15 is a programmer's model (register map) of all registers in the DMA
module. Each channel has an independent set of registers. For more information about a
particular register, refer to the individual register description. The ADDRESS column
indicates the offset of the register from the base address of the DMA channel. The FC
column designation of S indicates that register access is restricted to supervisor only. A
designation of S/U indicates that access is governed by the SUPV bit in the module
configuration register (MCR).
Unimplemented memory locations return logic zero when accessed. All registers support
both byte and word transfers.

1. To cause another DMA transfer, the DREQx is asserted after DACKx is asserted and before DACKx is negated.
2. DACKx and DONEx (DMA control signals) are asserted in the source (read) DMA cycle.
