MCU FLASH PROGRAMMING CONFIGURATION
To facilitate the possibility of down loading software into the application memory (MCU EEPROM or Flash), the SBC allows
the following capabilities: The VDD1 can be forced by an external power supply to 5.0 V and the reset and WDOG output by
external signal sources to zero or 5.0 V without damage. This supplies the complete application board with external power supply
and applies the correct signal to the reset pin.
