78K0R – Save It!
2.3 SW2
SW2 is a 3 position switch to set following modes.
2.4 SW3
SW3 is an 8 position DIP switch with following functions
Note: Make sure to set the regarding pull-up resistor option registers (PUx) of the microcontroller if
the Pins P33, P42, P43, P76 and P77. Please refer to the
78K0R/Kx3-L for detailed information about the pull-up resistor option register settings.

2.5 SW4 (Reset switch)

SW4 is connected to the external reset pin of the µPD78F1009 microcontroller. External reset can be
triggered by pushing.

2.6 SW5 (INTP0)

SW5 is connected to the "P120/INTP0/EXLVI" pin of the µPD78F1009 microcontroller. It can be used as
external interrupt source.
Note: Make sure to set up the microcontroller internal pull-up resistor option register (PU12)
correctly when using this external switch. Please refer to the
78K0R/Kx3-L for detailed information about the pull-up resistor option register settings.
