AMBA DMA Controller DMA-330 Technical Reference Manual: 4.2. Instruction set summary

4.2. Instruction set summary

The DMAC instructions:

use a DMA prefix, to provide a unique name-space
have 8-bit opcodes that might use a variable data payload of 0, 8, 16, or 32 bits
use suffixes that are consistent.

Table 4.1 shows a summary of the instruction syntax.
