Use the `offset` to access other bytes,

| MB address | Returns | offset byte |
| --- | --- | --- |
| 240 | 16 bit integer (2 bytes) | 0 |
| 241 | 16 bit integer (2 bytes) | 2 |
| 242 | 16 bit integer (2 bytes) | 4 |
| 243 | 16 bit integer (2 bytes) | 6 |
| 244 | 16 bit integer (2 bytes) | 8 |
| 245 | 16 bit integer (2 bytes) | 10 |
| 246 | 16 bit integer (2 bytes) | 12 |
| 247 | 16 bit integer (2 bytes) | 14 |
| 248 | 16 bit integer (2 bytes) | 16 |
| 249 | 16 bit integer (2 bytes) | 18 |
| 250 | 16 bit integer (2 bytes) | 20 |
| 251 | 16 bit integer (2 bytes) | 22 |
| 252 | 16 bit integer (2 bytes) | 24 |
| 253 | 16 bit integer (2 bytes) | 26 |
| 254 | 16 bit integer (2 bytes) | 28 |
| 255 | 16 bit integer (2 bytes) | 30 |
| 256 | 16 bit integer (2 bytes) | 32 |
| 257 | 16 bit integer (2 bytes) | 34 |

e.g...
