Peripheral UARTs[edit | edit source]

Description[edit | edit source]

The Universal Asynchronous Receiver/Transmitter (UART) interface available on MITO 8M Mini/Nano is based on iMX8M Mini/Nano SoC.

UARTs provides serial communication capability with external devices and support NRZ encoding format, RS485 compatible 9 bit data format and IrDA-compatible infrared slow data rate (SIR) format.

The UART port supports the following standards and features:

  • High-speed TIA/EIA-232-F compatible, up to Mbit/s
  • Serial IR interface low-speed, IrDA-compatible (up to 115.2 Kbit/s)
  • 9-bit or Multidrop mode (RS-485) support (automatic slave address detection)
  • 7 or 8 data bits for RS-232 characters, or 9 bit RS-485 format
  • 1 or 2 stop bits
  • Programmable parity (even, odd, and no parity)
  • Hardware flow control support for request to send (RTS_B) and clear to send (CTS_B) signals
  • Two independent, 32-entry FIFOs for transmit and receive
