Digital UART Ports
The device supports two digital UART ports. Use of these ports is determined by
the device type choice made in firmware. The details of the ports can be seen in
Table 3.
The availability of UART2 is selected in firmware.
The primary UART supports a 4-wire interface; the secondary port supports a 4-
wire interface except when being used with the Serial Device type, in which case
it is reduced to a 2-wire only.
The primary digital UART can be used as the primary connection for the Serial
device type. This type supports a 7-wire interface to allow the definition of the
serial interface type (RS232/3422/485) and the data transfer direction. Definitions
of this interface can be seen in Table 3.
The UART1 and UART2 interfaces support the following possible configurations:



Ethernet PHY Port
A 10/100 Ethernet PHY interface is supported on all device types (except SPI), it
is enabled by default when the Ethernet device type is selected in firmware. This
interface is a 10/100Mbps interface that supports auto negotiation and cross-over
cabling. The interface also supports both half and full duplex for 10Mbps and
100Mbps.
The interface uses a Broadcom BCM5241A Ethernet PHY, please refer to the
manufacturers datasheet for interface details and appropriate design guidelines.
