Universal Asynchronous
Receiver/Transmitters (UARTs)
Two 16550-compatible UARTs are supplied. One
provides asynchronous HDLC (High-level Data Link
Control) protocol support for full duplex transmit and
receive. The HDLC receiver handles framing, address
matching, CRC checking, control-octet transparency, and
optionally passes the CRC to the host at the end of the
packet. The HDLC transmitter handles framing, CRC
generation, and control-octet transparency. The host
must
transmission. The HDLC receiver and transmitter use the
UART FIFOs to buffer the data streams. The second
UART provides IrDA

Dual Port USB Host
The USB Open Host Controller Interface (Open HCI)
provides full speed serial communications ports at a
baud rate of 12 Mbits/sec. Up to 127 USB devices
(printer, mouse, camera, keyboard, etc.) and USB hubs
can be connected to the USB host in the USB “tiered-
start” topology.
This includes the following feature:

Table F. Universal Asynchronous Receiver/Transmitters Pin
UART1 supports modem bit rates up to 115.2 kbps,
supports HDLC and includes a 16 byte FIFO for
receive and a 16 byte FIFO for transmit. Interrupts are
generated on Rx, Tx and modem status change.
UART2 contains an IrDA encoder operating at either
the slow (up to 115 kbps), medium (0.576 or 1.152
Mbps), or fast (4 Mbps) IR data rates. It also has a 16
byte FIFO for receive and a 16 byte FIFO for transmit.
