16.2.6.1 DMA Channel to PaRAM Mapping
The mapping between the DMA channel numbers and the PaRAM sets is a fixed, one-to-one mapping
(see Table 16-5). In other words, channel (event) 0 is mapped to PaRAM set 0, channel (event 1) is
mapped to PaRAM set 1, etc. So, for example, in order to program a transfer for event number 3, DMA
channel 3 is associated with PaRAM set number 3 and you need to program this PaRAM set for
configuring transfers associated with event number 3. See your device-specific data manual for the
addresses of the PaRAM set entries.
