BQ76PL455A-Q1: program UART Baud rate

Part Number: BQ76PL455A-Q1

Team,

can I save baud rate to 125kb/s as default value??

I would like to boot up system and operate in 125kb/s.

current status is 250kb/s when I restart the system.

    Hi Marco,

    Yes, the register values can be stored to EEPROM, so that they will be the new default. In this way, 125KHz can be the default baud rate after startup. However, please be aware that when a COMM_RESET is issued, the baud rate will be changed to 250KHz and the host will need to use this baud rate to continue to communicate with the device.

    I hope this answers your question.

    Regards,

    Stephen

    Holland,
    one more question, can BQ76PL455A-Q1 GUI change baud rate to 125kb/s as default?
    when I changed IC baud rate to 125kb/s, launch BQ76PL455A-Q1 GUI, and select COM port and communication off.
    is there any way to fix this?
