4.11 UART

The i.MX8M Mini offers

four separate UART interfaces that are linked to the SMARC™ connector, two of them with Hardware flow control support

signals.

The UART interfaces supports Serial RS-232NRZ mode, 9-bit RS-485 mode or IrDA mode and includes the following features amongst others:

•

High-speed TIA/EIA-232-F compatible, up to 5.0 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

•

RS-485 driver direction control via CTS_B signal

•

Edge-selectable RTS_B and edge-detect interrupts

•

Status flags for various flow control and FIFO states

•

Voting logic for improved noise immunity (16x oversampling)

•

Transmitter FIFO empty interrupt suppression

•

UART internal clocks enable/disable

•

Auto baud rate detection (up to 115.2 Kbit/s)

•

Receiver and transmitter enable/disable for power saving

•

RX_DATA input and TX_DATA output can be inverted respectively in RS-232/RS-485 mode

•

Maskable interrupts

•

Two DMA Requests (TxFIFO DMA Request and RxFIFO DMA Request)

•

Escape character sequence detection

•

Software reset (SRST_B)

•

Two independent, 32-entry FIFOs for transmit and receive
