| help |
| Enable partial erase feature. Partial erase is performed in time |
| slices instead of blocking MCU, for the time it is needed to |
| complete operation over given area. |
| This allows interrupting flash erase between operations |
| to perform other task by MCU. |
| This feature may also be used for better syncing flash erase |
| operations, when compiled with SOC_FLASH_NRF_RADIO_SYNC_TICKER, |
| with Bluetooth. |
