Serial Port: Standard-Bandwidth: UART

The NTx-Pro IP Engine supports Universal asynchronous receiver/transmitter (UART) serial communi-
cation. The UART signal and timing requirements are explained in the sections that follow.

Signals

The standard serial port communication uses the following signals:

•

UART

_TXD

•

UART

_RXD

•

DGND (return)

Timing for UART

The NTx-Pro IP Engine supports these UART protocols:

•

8-bit data transfer

•

1 start bit

•

Any parity (even, odd, or none)

•

1 or 2 stop bits

UARTx_TXD
UARTx_RXD

START

Parity STOP
