For each X, the setting for this switch makes no difference, because it is not used.
Address
Switch SW15 or SW16 and logic on the card always address the four
UARTs using a pair of addresses: 0 and 1, 2 and 3 through 14 and 15.
The settings for both switches are shown in Table 288 "NT8D41BA
address switch settings" (page 727). To avoid system problems,
switches SW15 and SW16 must not be configured identically. Figure 246
"NT8D41BA QSDI paddle board" (page 723) displays SW15 and SW16.
