The diagrams in this section describe how the DMA engine performs write accesses of an external peripheral. The CLK signal shown is for reference, and its frequency is equal to the speed grade of the part. For peripheral writes, the PDEN signal is an AND function of the active status of st_cs_n[n] and we_n. Write data into the peripheral on the falling edge of the PDEN signal. Data and control signals are always held after the falling edge of PDEN for one reference CLK cycle.
