Memory Map and Register Definition

This section provides a detailed description of all memory-mapped registers in the DMA Mux.

Table 27-2 shows the memory map for the DMA Mux. Note that all addresses are offsets; the absolute

address may be computed by adding the specified offset to the base address of the DMA Mux.

All registers are accessible via 8-bit, 16-bit or 32-bit accesses. However, 16-bit accesses must be aligned

to 16-bit boundaries, and 32-bit accesses must be aligned to 32-bit boundaries. As an example,

CHCONFIG0 through CHCONFIG4 are accessible by a 32-bit READ/WRITE to address ‘Base + 0x00’,

but performing a 32-bit access to address ‘Base + 0x01’ is illegal.

27.3.1

The following memory-mapped registers are available in the DMA Channel Mux.

27.3.1.1

Channel Configuration Registers

Each of the total of 16 DMA channels can be independently enabled/disabled and associated with 1 of the

30 total DMA sources in the system.
