Boot Option
During power-on-reset the XMC4200 latches the signal level at the pins TMS and TCK. Based on the logic levels
latched at these pins after reset the XMC4200 starts booting in different modes. TMS and TCK pins are used for
debugging and by default program execution is always starting from on-chip flash (normal mode).
The XMC4200 Platform2Go Series-V1.1 does not support the selection of the boot options by switches directly.
In case of no external debug probe is used the boot mode can be influenced by applying 1 kOhm pull-up- or pull-
down resistors to TMS and TCK pins. These pins are available at the 10-pin debug connector X102.
