These inputs control the information contained in Bits[31:24] of the Control words
generated by the Transmitter. The value of CTL_TX_MUBITS[0] appears in
Bit[24] of the next Control Word generated by the TX. The value of
CTL_TX_MUBITS[1] appears in Bit[25], and so forth.
The values on CTL_TX_MUBITS are completely ignored when retransmission
is enabled by CTL_TX_RETRANS_ENABLE = 1.
The value of CTL_TX_MUBITS[7] is ignored when
CTL_TX_CHAN_EXT[1:0] = 2'h1.
The values of CTL_TX_MUBITS[7:6] are ignored when
CTL_TX_CHAN_EXT[1:0] = 2'h2.
The values of CTL_TX_MUBITS[7:5] are ignored when
CTL_TX_CHAN_EXT[1:0] = 2'h3.
