2.9.4 Switch Settings

Here follows explanations of the switches of the emulation pod. Set the switches according to the user system.
Tables 2.3 and 2.4 list how to set toggle switches SW1 to SW5 of the M30620T3-PRT board (MCU-dependent board 1). Table
2.5 lists how to set jumper switches JP1 and JP2. For the positions of the switches, see Figure 2.18.
