TXG3[3:0] Transmit Gain 3.
Reserved Read returns zero.
Name
TGA3
D7
Transmit Gain or Attenuation 3.
0 = Incrementing the TGA3[3:0] bits results in gaining up the transmit path.
1 = Incrementing the TGA3[3:0] bits results in attenuating the transmit path.
Each bit increment represents 0.1 dB of gain or attenuation, up to a maximum of 1.5 dB.
