Message FIFO.
Contains message to be transmitted or message received.
LNB Supply Low Voltage.
Low voltage = Vlow_nom + VLOW[3:0] x 0.0625V + Vboost, where
Vlow_nom is determined by the LNBV(C0h[6]) register bit, and Vboost
is determined by the COMP(CEh[2]) register bit.
Default: Low voltage = Vlow_nom + 0.0 V + Vboost.
LNB Supply High Voltage.
High voltage = Vhigh_nom + VHIGH[3:0] x 0.0625V + Vboost, where
Vhigh_nom is determined by the LNBV(C0h[6]) register bit, and
Vboost is determined by the COMP(CEh[2]) register bit.
Default: High voltage = Vhigh_nom + 0.0 V + Vboost.
