h1. EEPROM

The STM32L011x4 has 512Bytes EEPROM

Campo spezifies 0x20 bytes of HWData, 0x20 Bytes of Board specific stuff, and 2*0x20 config data.

Page size (erase size) of EEPROM is 4 bytes.

Retain block is 8 Bytes, so still 0x18 Bytes for I2C-EEPROM-compatible layout.

| 0x6     | 2     | Slot 2: Time (Egg)            |

| 0x8     | 2     | Slot 3: Time (Weisswurst)     |

| 0xA     | 2     | Slot 4: Time (Nudeln 1)       |

| 0xC     | 2     | Slot 5: Time (Nudeln 2)       |

| 0xE     | 2     | Slot 6: -                     |

| 0x10    | 4     | long time 1 depending on mode |

| 0x14    | 4     | long time 2 depending on mode |

| 0x18    | -     |                               |

4 bytes gives a range > 24h.
