(2) Setting SW5 on the M30850T2-EPBM
Table 2.3 lists the examples of setting the switch SW5. It is necessary to change the setting if using the analog input port
selection function of the A/D converter.
Setting the SW5 enables to set each analog input pin for selecting an analog input port. When selecting AN00 to AN07 or
AN20 to AN27 for the analog input port select bits (bit 2 and bit 1 of 0394h), set the pins used for A/D conversion to ON,
the pins not used to OFF.
