SAM9G46
The Peripheral DMA Controller handles transfer requests from the channel according to the fol-
lowing priorities (Low to High priorities):
Table 6-6.
The SAM9G46 features USB communication ports as follows:
USB Host Port A is directly connected to the first UTMI transceiver.
The Host Port B is multiplexed with the USB device High speed and connected to the second
UTMI port. The selection between Host Port B and USB device high speed is controlled by a the
bit UDPHS enable bit located in the UDPHS_CTRL control register.
