CCS/CC2652R: where can i refer the value of init params

Tool/software: Code Composer Studio

HI,

when i init the driver , I don't know how many kind of  value with param that i can choose.

for example: 

UART_Params_init(&uartParams);
uartParams.writeDataMode = ?;
uartParams.readDataMode = ?;
uartParams.readReturnMode = ?;
uartParams.readEcho = ?;
uartParams.baudRate = ?;

if there is a doc. refer to?

thanks.
