| description: |
| If concatenation buffer size is set, then multiple messages in the |
| same direction will be concatenated into single transfers as long |
| as there is space in buffer and no restart or stop flag is set. |
| |
| This property must be provided when interacting with devices like |
| the SSD1306 display that cannot tolerate a repeated start and |
| address appearing on the bus between message fragments. For many |
| devices a concatenation buffer is not necessary. |
