TYP (Type): This field indicates the type of source to be used for a DMA transfer. Different
fields within the DSAT register are used depending on the type of source selected.
shows the different source types and the associated fields within the DSAT register that apply.
Table 153: DSAT TYP Encoding
PSZ (Pattern Size): If set, the data size used during Data Pattern transfers is bytes (8-bit). If
cleared, the data size is words (32-bit). This field only applies to the generation of the data
patterns used for a transfer. It does not specify how the patterns are actually placed into the
destination space. (that is, selecting a byte pattern size does not result in a stream of
single-beat bus cycles.)
NIP (No Increment Pattern): If set, and the source is a data pattern, then the data pattern,
will not be incremented. If cleared and the source is a data pattern, the data pattern will be
incremented.
