Function

Baud-rate range 0 (B0) 1.0 kBaud to 2.5 kBaud;

XDCLK = 8 × TDCLK × XLim

Baud-rate range 1 (B1) 2.0 kBaud to 5.0 kBaud;

XDCLK = 4 × TDCLK × XLim

Baud-rate range 2 (B2) 4.0 kBaud to 10.0 kBaud;

XDCLK = 2 × TDCLK × XLim; (default)

Baud-rate range 3 (B3) 8.0 kBaud to 20.0 kBaud;

XDCLK = 1 × TDCLK × XLim,

Note that the receiver is not working with >10 kBaud in ASK mode
