Universal Platform SOC Processor
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.
UART3 supports HDLC and includes a 16 byte FIFO
for receive and a 16 byte FIFO for transmit. Interrupts
are generated on Rx and Tx.
Triple-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
star” topology.
This includes the following features:
Compliance with the USB 2.0 specification
Compliance with the Open HCI Rev 1.0 specification
Supports both low speed (1.5 Mbps) and full speed
(12 Mbps) USB device connections
Root HUB integrated with 3 downstream USB ports
Transceiver buffers integrated, over-current protection
on ports
Supports power management
Operates as a master on the bus
The Open HCI host controller initializes the master DMA
transfer with the AHB bus:
Fetches endpoint descriptors and transfer descriptors
Accesses endpoint data from system memory
Accesses the HC communication area
Writes status and retire transfer descriptor
Two-wire Interface
The two-wire interface provides communication and
control for synchronous-serial-driven devices.
Real-time Clock with Software Trim
The software trim feature on the real time clock (RTC)
provides software controlled digital compensation of the
32.768 KHz input clock. This compensation is accurate to
±
1.24 sec/month.
Note:
A real time clock must be connected to RTCXTALI or
the EP9312 device will not boot.
PLL and Clocking
The Processor and the Peripheral Clocks operate from a
single 14.7456 MHz crystal.
The Real Time Clock operates from a 32.768 KHz
external oscillator.
