Description
reserved for future use
selects the input of drivers TX1 and TX2
DriverSel[1:0]
3-state; in soft power-down the drivers are only in 3-state
mode if the DriverSel[1:0] value is set to 3-state mode
modulation signal (envelope) from the internal encoder, Miller
pulse encoded
modulation signal (envelope) from pin MIFIN
HIGH; the HIGH level depends on the setting of bits
