DSP GDMA Handler Input Line

The mapping of the DSP DMA requests is done through the

FUNC_MUX_DSP_DMA_X registers (shown in Table 11), which are

implemented in the configuration module. Table 12 through Table 15 describe

the register bits.

The values programmed into these registers represent a zero-based

numbering of the DMA request. Thus, peripheral request number n is

programmed as n-1, not n.

Base Address = 0xFFFE 1000
