The data rate (in bps) and the decimal value to be coded in the register are related by
the equation:

The following table gives the programming values of commonly used rates:

Wake Up Address Register
(WUA)

Concerning this register, attention should be paid to the fact that the last bit of the
address field is not taken into account when testing the address field that is received.
Thus the last bit must be programmed and counted in the address length but it can be
either "0" or "1".
