For example, to switch Layer1-B1 to/from PCM2/GCI_B2 : First look at Layer1-B1 receive table, we find that PXC=1 and
B1_SW[1:0] = 01 in order to receive PCM2/GCI_B2. Secondly look at PCM2/GCI_B2 receive table, we find that, to receive
L1_B1, there are two combinations of PXC, B1_SW[1:0] : 100 or 101. The logical AND result of these two tables is PXC=1,
B1_SW[1:0]=01. This is the value which must be programmed in the registers.
