Serial Interfaces
The phyCARD-M provides seven serial interfaces some of which are
equipped with a transceiver to allow direct connection to external
devices:
1.
High speed UART (TTL, derived from UART1 of the i.MX35)
with up to 4.125Mbit/s and hardware flow control (RTS and CTS
signals)
2.
High speed USB OTG interface extend from the i.MX35 USB
OTG interface
3.
Full speed USB HOST interface using the i.MX35's internal USB
Host interface, or optional high speed USB HOST interface
derived from an external USB HOST controller at U16.
4.
Auto-MDIX enabled 10/100 Ethernet PHY supporting the
i.MX35 Ethernet MAC
5.
I
2
C interface (derived from third I
2
C port of the i.MX35)
6.
Serial Peripheral Interface (SPI) interface (extended from the first
SPI module of the i.MX35)
7.
Synchronous Serial Interface (SSI) with AC97 support
(originating from the synchronous serial interface of the i.MX35)
The following sections of this chapter detail each of these serial
interfaces and any applicable configuration jumpers.
