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 UART supports 9-bit characters in addition to the 5- to 8-bit characters that other UARTs support. This was introduced by Oxford Semiconductor, which is now owned by PLX Technology.
These type of baud rate detection mechanism are supported by many hardware chips including processors such as STM32 [1] MPC8280, MPC8360, and so on. When start bit length is used to determine the baud rate, it requires the character to be odd since UART sends LSB bit first – this particular bit order scheme is referred to as little-endian. [2]
The STM32 F7-series is a group of STM32 microcontrollers based on the ARM Cortex-M7F core. Many of the F7 series are pin-to-pin compatible with the STM32 F4-series. Core: ARM Cortex-M7F core at a maximum clock rate of 216 MHz. Many of STM32F76xxx and STM32F77xxx models have a digital filter for sigma-delta modulators (DFSDM) interface. [31]
An example of a USART. A universal synchronous and asynchronous receiver-transmitter (USART, programmable communications interface or PCI) [1] is a type of a serial interface device that can be programmed to communicate asynchronously or synchronously.
The 16550 UART (universal asynchronous receiver-transmitter) is an integrated circuit designed for implementing the interface for serial communications. The corrected -A version was released in 1987 by National Semiconductor . [ 1 ]

The number of bits per character -- currently almost always 8-bit characters, but historically some transmitters have used a five-bit character code, six-bit character code, or a 7-bit ASCII. Endianness: the order in which the bits are sent; The speed or bits per second of the line (equal to the Baud rate when each symbol represents one bit).
