LINKS
Link options can be set to change the configuration of the
circuits. Table 2 shows the positions in which all the links are
set when the evaluation boards are shipped.
The functions of these link options are summarized in Table 3.
The positions of the links can be changed when the evaluation
board is connected to the power supply.
