Protocolo de comunicación

Dear Sirs,

I'm trying to implement a communication protocol, called DALI is an open standard that is used for lighting (to vary the light output of an electronic ballast), is structured as follows: The communication speed is 1200 bit / sec.

Transmission: 19 bits:

1 start bit, 1 byte address, 1 byte of data, 2 stop bits.

Reception: 11 bits: 1 start bit, 1 byte of data, 2 stop bits.

My question is how could implement, as the serial communications uses 8 data bits. I'm lost if someone could help me appreciate it.

Thanks. Greetings.
