Table 7. Signal Functional Description (Part 7 of 10)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3kΩ to OV
3. Must pull down (recommended value is 1kΩ)
4. If not used, must pull up (recommended value is 3kΩ for LVTTL or 8.2kΩ for PCI to OV
5. If not used, must pull down (recommended value is 1kΩ)
6. Strapping input during reset; pull-up or pull-down required

UART Peripheral Interface
The UART interface can be configured as follows:
1. One 8-pin, where n = 0
2. Two 4-pin, where n = 0 & 1
3. Four 2-pin, where n = 0 & 1 & 2 & 3

Signal Name
Receive data.
Bidirectional Device data bus.
Transfer direction. PHY has data to transfer.
This input provides an alternative to the internally generated
serial clock. It is used in cases where the allowable internally
generated clock rates are not satisfactory.
Transmit data.
Data Carrier Detect.
Data Set Ready.
Clear To Send.
Data Terminal Ready.
Request To Send.
Ring Indicator.
IIC0 Serial Clock.
IIC0 Serial Data.
Next transfer. Input signal from the PHY:
Stop transfer. Output signal to the PHY:
USB 2.0 OTG clock—60MHz.
Receiving—ready to accept the next data transfer.
Transmitting—a new byte is ready to send.
Receiving—stop transferring data.
Transmitting—the last byte of data has been sent.
