4 Jumpers and Switches
This chapter describes all jumpers and switches that can be modified on the adapter board.
The default setting (MB91270 Series) is shown with a grey shaded area. All jumpers and
switches are named directly on the board, so it is very easy to set the jumpers according to
the features.
4.1 Operating-Mode (S2)
The DIP-switch S2 is used to set the operating mode of the µC. Ensure that the mode pin
settings correspond to the operation-mode of the application. For more detailed information
please check the Hardware-Manual of the microcontroller.

Note: The low-level for serial programming is reached by the pull-down resistors R28 and R29 that are enabled by the
jumpers JP50 and JP51. Please refer to chapter 5 (Programming the internal Flash) for more details about the operation mode.
