Analog gain in transmit direction
AGX = 0:
analog gain is disabled
AGX = 1:
analog gain is enabled (6,02dB amplification)
Analog gain in receive direction
AGR = 0:
analog gain is disabled
AGR = 1:
analog gain is enabled (6,02dB attenuation)
Disable highpass in transmit direction
D-HPX = 0: transmit high pass is enabled
D-HPX = 1: transmit high pass is disabled
