// We're going to write one byte (subaddress)
// EEPROM reading - Function (search min and max / function)
// We're going to read 2 bytes (length of descriptor + Function)
// Min and Max search for function 0
// Min and Max search for function 1
// Min and Max search for function 2
// Min and Max search for function 3 (not defined in the EEPROM)
// End of data in the EEPROM
// EEPROM reading - Data in a specified function
// We're going to read one byte (length of descriptor)
// Read the EEPROM
// Buffer4[0] contains the length of the descriptor
// First byte of data is the descriptor length
// Read the entire descriptor from the eeprom
// Buffer4 contains the data from the eeprom
// ----------------------------------------------------------
// At this point we have the data from the eeprom in Buffer4
