Transmit Gain or Attenuation 2.
0 = Incrementing the TXG2[3:0] bits results in gaining up the transmit path.
1 = Incrementing the TXG2[3:0] bits results in attenuating the transmit path.
3:0
TXG2[3:0] Transmit Gain 2.
Each bit increment represents 1 dB of gain or attenuation, up to a maximum of +12 dB
and –15 dB respectively.
For example:
