Uart star and stop bit.

Hello,

Is there’s a way how I can send a minimum of 11 (LOW) bits over the UART without being interrupted by the UART’s start and stop bit? Do i need to modify some UART setting even though in general UART automatically adds start and stop bit and it cannot be removed. I really need at the beginning of communication to get 13-26 (LOW bits) followed by standard serial communication .

Regards,
