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.
