Chapter 7 Enhanced Direct Memory Access (eDMA) Controller
Figure 7-2. Crossbar switch configuration
The crossbar switch forms the heart of this multi-master architecture. It links each master
to the required slave device. If both masters attempt joint access to the same slave, an
arbitration scheme commences eliminating the bus contention. Both fixed priority and
round robin arbitration schemes are available. If both masters attempt to access different
slaves, an arbitration scheme works for the judgement.
7.2 eDMA trigger
Each channel of the Kinetis eDMA module can be triggered to start DMA transfer of
multiple sources from peripherals or software. The eDMA module integrates the DMA
Mux to route a different trigger source to the 16 channels. With the DMA Mux, up to 63
events occurring within other peripheral modules can activate an eDMA transfer. In
many modules, event flags can be asserted as either eDMA or Interrupt requests. These
sources can be selected through DMAMUX_CHCFGn[SOURCE] registers. But different
devices may have different peripheral source configurations. Refer to the device-specific
reference manual for details.
