Reference Using Or Bypassing Flow Control With Uart Communication Silicon Labs From community.silabs.com
If the baudrate could be reduced thatll be a very good place to start. In learning the use of the 8515 interrupt driven UART in assembly language in became apparent why flow control is important in RS232. The software flow control uses a pair of control characters - XONXOFF. Thanks My system is configurable by the user for flow control and hence need to implement it. I see the flow-control recommendation in SLAU647 as you mention but I think given your use of a 8MHz MCLK you may be able to get higher speeds without flow control this may be a limitation of the MSP-FET. The flow control valid values are UART_FLOW_NO UART_FLOW_SOFTWARE or UART_FLOW_HARDWARE.

The software flow control uses a pair of control characters - XONXOFF. Universal asynchronous receivertransmitter UART UART peripherals typically have several configurable parameters required to support different standards. Baud rate is the number of symbols or modulations per second. 1 - Arduino to receive one or few bytes and sends a XOFF to the PC Windows is set to software flow control 2 - Arduino would process the received bytes eg. The software flow control uses a pair of control characters - XONXOFF. The two symbols UARTDRV_FC_SW_XON and UARTDRV_FC_SW_XOFF are defined in uartdrv_configh.

Hardware flow control uses dedicated signal wires such as RTSCTS or DTRDSR while software flow control signals by sending DC1 or DC3 control bytes in the normal data wires. One of these is to use an interrupt driven UART send and receive technique and queue the data flow between the application mainline code and the interrupt routines through circular FIFO buffers. Search around for software flow control in say Google. Hardware flow control is a form that uses extra wires. UART software flow control uses in-band signaling meaning the receiver sends special flow control characters to the transmitter and thereby removes the need for dedicated wires for flow control.

The problem with consideration of characters already transmitted is that theirs a chance that the remote system has already requested to. Hardware and software XonXoff or DC1DC3. There should be no hardware flow control in the RS485 standard. Deasserted is 33V or high. Search around for software flow control in say Google.

Flow control here means RTSCTS which would be implement in Software on the MCU side since theres no hardware support for these signals in the eUSCI peripheral. UART software flow control XONXOFF is partially supported by the driver the application should monitor the received data during the data transmission and pause or resume the transmitter after receiving XOFF or XON. Since the API is shared with the RS232C standard it can be called but it will not work effectively. One of these is to use an interrupt driven UART send and receive technique and queue the data flow between the application mainline code and the interrupt routines through circular FIFO buffers. The FTDI chip has built-in hard- and software to handle software flow control XONXOFF internally.
