Transmit data
VCO band switch control signal.
LMX3162 DC compensation circuit enable. This signal is enabled (low) throughout
the correlation phase.
LMX3162 DC compensation circuit enable. At the beginning of the correlation
phase this signal is enabled (low) for 15 µs. For the remainder of the correlation
phase this signal is PWM by 1/8 (cycle time = 1 µs).
LMX3162 4 MHz oscillator input to the PLL synthesizer. This signal is only
enabled when the LMX3162 is active.
MICROWIRE
MICROWIRE load enable to LMX3162.
MICROWIRE clock to LMX3162.
LMX3162 PLL power down. This signal is used to open the PLL loop or powering
down the PLL. The PLL loop is opened when transmitting to make it possible to
FSK modulate the VCO. When receiving it is optional to open the PLL loop
(configured by the PLLOpenRX bit in threshold_msb).
LMX3162 Transmitter power down. For power conservation, the Transmitter is
only powered during Transmit Frames.
LMX3162 Receiver power down. For power conservation, the Receiver is only
powered during Receive Frames.
LMX3162 chip enable. When the LMX5001 is in Idle Mode the LMX3162 is
powered down.

Antenna switch control.
Antenna switch control. This signal is RFSW1 inverted,
Switches the external PA on/off for 20 dBm/0 dBm transmission, respectively.
