| a specific FLASH interface that requires aligned read access. |

| help |
| If selected, writing to a non-erased program unit will succeed, otherwise, it will return an error. |
| Keep in mind that write operations can only pull bits to zero, regardless. |

| help |
| Only up to this number of beginning pages will be tracked |
| while catching dedicated flash operations and thresholds. |
| This number is not automatic because implementation uses |
| UNTIL_REPEAT() macro, which is limited to take explicitly |
| number of iterations. |
| This is why it's not possible to calculate the number of pages with |
| preprocessor using DT properties. |
