1.4.1 Define µC Operating Mode
The DIP switch S1 is used to set the operating mode of the µC and to configure
the two serial interfaces. S1/1, S1/2 and S1/3 are used to set the three mode pins
MD0, MD1, MD2 of the microcontroller. These mode pins define the operating
mode of the µC. Make sure that the mode pin setting corresponds to the usage of
the application. For more detailed information please look at the Hardware
Manual of the microcontroller series. The default setting is used for 'Single Chip'
normal mode.
MD0 (S1/1)
MD1 (S1/2)
MD2 (S1/3)

S1/7 and S1/8 are used to set the port pins P00 and P01. These two port pins are
used to define the serial programming mode, if the In-Circuit serial programming
of the Flash memory is used. For normal operation these port pins are used as
general I/O ports.
Note: The port pins P01 and P00 are connected to a 47K pull up resistor
each.
