4. `block_size=9` The block size reported to the filesystem. The size in bytes
is `2**block_size` so is 512 bytes by default.
5. `addr` override base address for first chip
6. 'max_chips_count` override max_chips_count
6. `max_chips_count` override max_chips_count
With `addr` and `max_chips_count` override, it's possible to make multiple
configuration
example:
array with custom chips count:
```python
eeprom0 = EEPROM( i2c, max_chips_count=2 )
eeprom1 = EEPROM( i2c, addr=0x52, max_chips_count=2 )
```
1st array using address 0x50 and 0x51 and 2nd using array address 0x52 and 0x53.
individual chip usage:
```python
eeprom0 = EEPROM( i2c, addr=0x50, max_chips_count=1 )
eeprom1 = EEPROM( i2c, addr=0x51, max_chips_count=1 )
```
### 4.1.2 Methods providing byte level access
It is possible to read and write individual bytes or arrays of arbitrary size.
