Power Up Configuration
The S32V234 is configured during power up by the state of 32 I/O signals, which
are controlled by the MCU. Within the MCU, the four most popular RCON boot
configurations are implemented and can be selected via the dip-switch BOOT
placed on the carrier board.
These configurations are only valid, if the Boot Mode Configuration is set to RCON Boot!
