Alternative Boot EEPROM + + Upon the kmeter1 startup the I2C_1 controller is used to fetch the boot + configuration from a serial EEPROM. During the development and debugging + phase it might be helpful to apply an alternative boot configuration in + a simple way. Therefore it is an alternative boot eeprom on the PIGGY, + which can be activated by setting the "ST" jumper on the PIGGY board. + +2.
