SAM9G35 Master to Slave Access
SMD
All the Masters can normally access all the Slaves. However, some paths do not make sense,
for example allowing access from the USB Device High speed DMA to the Internal Peripherals.
Thus, these paths are forbidden or simply not wired, and shown as “-” in the following table.
The SAM9G35 features the following USB communication ports:
The High Speed USB Host Port A is shared with the High Speed USB Device port and con-
nected to the second UTMI transceiver. The selection between Host Port A and USB Device is
controlled by the UDPHS enable bit (EN_UDPHS) located in the UDPHS_CTRL control register.
• 2 Hosts (A and B) High Speed (EHCI) and Full Speed (OHCI)
• 1 Host (C) Full Speed only (OHCI)
• 1 Device High Speed
