Figure 4.8-50 shows a setting example of an improper setting of the 43SW scheme. The settings
are implemented incorrectly as shown in Table 4.8-30, BO1-RB is not chosen, instead BO1 is
actually chosen, which is incorrect. In this case, the setting [DPOS01-OSLBORD] is
meaningless ; hence, the issue of a select command is blocked.
