Why is UART communication faster than Default Baudrate even though we haven't changed setting?

Hi Support,

Thank you for your usual support.
I have questions,could you please answer below?

Target: USB-UART Controller CY7C65213
The Internal flash memory is used with default values.
(Meaning that it is not intentionally rewritten by the Utility)

1. Is the Default Baudrate of this Device 115200?
2. UART communication was possible at 3Mbps even though the Baudrate was not changed on the customer's board.Windows 10 PC ⇔ USB 12 Mbps ⇔ UART 3 Mbps
Is it possible that the default Baudrate will be 3Mbps even if it has not been changed with a utility?

3.My guess is that the default Baudrate is 115200, and UART communication should be limited to 115200. Why was the customer UART controller able to communicate with 3M without changing the settings?
