This USART has a 3-byte receive buffer and a 1-byte transmit buffer. It has hardware to accelerate the processing of HDLC and SDLC. The CMOS version (Z85C30) provides signals to allow a third party DMA controller to perform DMA transfers. It can do asynchronous, byte level synchronous, and bit level synchronous communications.

Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
RS-485, like RS-422, can be made full-duplex by using four wires. [8] Since RS-485 is a multi-point specification, however, this is not necessary or desirable in many cases. RS-485 and RS-422 can interoperate with certain restrictions.
Debugging requires a target chip with debug port and a debug probe. The official Arduino Zero board can be debugged out of the box. Other official Arduino SAMD21 boards require a separate SEGGER J-Link or Atmel-ICE. For a 3rd party board, debugging in Arduino IDE 2.0 is also possible as long as such board supports GDB, OPENOCD and has a debug ...

The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
