Microcontrollers configured as sub devices may have hardware support for generating interrupt signals to themselves when data words are received or overflow occurs in a receive FIFO buffer, [6] and may also set up an interrupt routine when their chip select input line is pulled low or high.
The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
LED: There is a built-in LED driven by digital pin 13.When the pin is high value, the LED is on, when the pin is low, it is off. VIN: The input voltage to the Arduino/Genuino board when it is using an external power source (as opposed to 5 volts from the USB connection or other regulated power source).
An all-in-one Arduino with motor controller. Compatible with the Arduino Uno. Roboduino [110] Designed for robotics. All connections have neighboring power buses (not pictured) for servos and sensors. Additional headers for power and serial communication are provided. It was developed by Curious Inventor, LLC. SunDuino [111]

The individual signals on a serial port are unidirectional and when connecting two devices, the outputs of one device must be connected to the inputs of the other. Devices are divided into two categories: data terminal equipment (DTE) and data circuit-terminating equipment (DCE). A line that is an output on a DTE device is an input on a DCE ...
This UART was introduced by Exar Corporation. Exar claims that early versions can run up to 2 Mbit/s, and later versions can run up to 2.25 Mbit/s depending on the date of manufacture. 16C850 16950 128-byte buffers. This UART can handle a maximum standard serial port speed of 921.6 kbit/s if the maximum interrupt latency is 1 millisecond. This ...
This provides up to 124 (4 x 31 = 124) input and 124 outputs on a standard device network (nodes addressed 1-31) or 248 (4 x 62 = 248) inputs and 248 outputs on an advanced network (nodes addressed 1A - 31A and 1B - 31B ). The serial communication is modulated onto the power supply. Manchester coding is used for the communication. For 31 ...
