Description
defines the minimum signal strength at the decoder input that will be
accepted
if the signal strength is below this level it is not evaluated
reserved for future use
defines the minimum signal strength at the decoder input that must be
reached by the weaker half-bit of the Manchester encoded signal to
generate a bit-collision relative to the amplitude of the stronger half-bit

Description
defines the use of I and Q channel during reception
Remark: the FixIQ bit must be set to logic 0 to enable the following
settings:
if AddIQ[1:0] are set to X0b, the reception is fixed to I channel
if AddIQ[1:0] are set to X1b, the reception is fixed to Q channel
reserved for future use
changes the time-constant of the internal PLL during data reception
Remark: if set to 00b the PLL is frozen during data reception
changes the time constant of the internal PLL during burst
R/W
selects the stronger channel
selects the stronger channel and freezes the selected channel
during communication
