Enable pull-down transistor in power-down mode
Battery detection high/low range
Mute TX low frequency path (compressor) keeping circuit enabled
Enable TX low frequency part
Gain of VCO2
Double phase comparator frequency of PLL2
Enable HF-transmit output
Changes 1 dB compression point and current consumption of Mixer1
(“0” –> high, “1” –> low)
Output frequency range of MixerT
Invert inputs of phase comparator in PLL2
Speed-up phase comparator for PLL1
Enable the internal test mode. It is mandatory that TM is kept to “0”!
(if not 0, the circuit will not work as expected or described here in this paper)
