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.
