78K0R/Lx3 – Sense it!
2.2.1 SW1
SW1 can set the signal that is connected to "- side" of microcontroller built-in operational amplifier 0 (AMP0 -
terminal).
SW1
DAC
Connect D/A converter (ANO0) to "- side" of microcontroller built-in operational
amplifier 0 (AMP0 - terminal).
GND
Connect "- side" of microcontroller built-in operational amplifier 0 (AMP0 - terminal) to
GND.
2.2.2 SW2
SW2 can set the input voltage for A/D converter (ANI１).
SW1
TEMP
Connect the output of temperature sensor to A/D converter (ANI１ terminal)
Ext Volt
Connect the voltage of J5 connector to A/D converter (ANI１ terminal)
2.2.3 SW3
SW3 can select if it uses microcontroller built-in operational amplifier 0 or not.

2.2.4 SW4 (Cursor)
SW4 is 4 Ways + Center-push Switch. It becomes "Low" when it is pushed or shifted to the side. It becomes
"Open" when it is released. You need to set microcontroller built-in pull-up option resistor (PU7) to "ON". (For
details about settings of microcontroller built-in pull-up option resistor, refer to the
78K0R/Lx3).
