Transmitter Digital Gain
These bits control the value of the digital gain section of the
73M1x66B transmit path. Each bit indicates either a gain or
attenuation value. The net value of the gain setting is the linear sum
of each attributed value. Reading the TXDG register returns all
zeros, regardless of what was written to them.
Examples:
Transmit Path Enable
1 = Enable Transmit Path.
0 = Disable Transmit Path. (Default)
10000000 -12dB
00100000 +3.5dB
00010011 +2 + 0.25 + 0.125 =2.375dB
01001000 -6 + 1 = -5dB
