AT91SAM9M10-G45-EK User Guide
User Serial Com Port
USB Port
The USART1 is used as a user serial communication port. This USART1 is buffered with an RS-232
Transceiver (TXD, RXD and handshake CTS/RTS control) and connected to the DB-9 male socket. Soft-
ware must assign the appropriate PIO pins (PB5 = RXD1, PB4 = TXD1, PD16 = RTS1, PD17 = CTS1) to
enable the UART1 function.
Figure 4-9.
Refer to the SAM9M10 datasheet for more information about the SAM9M10 USARTs.
The SAM9M10-G45-EK features USB communication ports:
USB Host Port0 is directly connected to the first UTMI transceiver. The second Host Port (Port1) is mul-
tiplexed with the USB Device High speed and connected to the second UTMI port.
Refer to the SAM9M10 datasheet for detailed programming information.
Two Host Ports: Full speed OHCI and High speed EHCI
One Device Port: High speed.
One USB high/full speed type standard A connector
One USB interface Host/Device Micro AB connector
