Erase EEPROM
The Write EEPROM Page command is used to write all locations that is loaded in the EEPROM
page buffer into one page in EEPROM. Only the locations that are loaded and tagged in the
EEPROM page buffer will be written.

The BUSY flag in the NVM STATUS register will be set until the operation is finished.
The Erase & Write EEPROM Page command is used to first erase an EEPROM page and write
the EEPROM page buffer into that page in EEPROM, in one atomic operation.
