This section describes the DMA signals.
16.2.1
Figure 16-3
Note that the three DMA signals for DMA channel 3 are multiplexed with the IRQ9–11 signals on the
device. These functions are mutually exclusive and the active function is specified in the PMUXCR
register of the global utilities block as described in
Multiplex Control Register (PMUXCR).”
