  Reads one byte from the given EEPROM address.

• void EEPROM_Write (eeprom_address_t address, eeprom_data_t data)

  Writes one byte to the given EEPROM address. The NVM busy status must be checked using the NVM_IsBusy() API to know if the write operation is completed.

• device_id_data_t DeviceID_Read (device_id_address_t address)

  Reads the Device ID.

• configuration_data_t CONFIGURATION_Read (configuration_address_t address)

  Reads one Configuration byte.

• nvm_status_t CONFIGURATION_RowRead (configuration_address_t address, configuration_data_t *dataBuffer)

  Reads all the Configuration Words. The size of the buffer must be one Configuration row/sector and the address must be aligned with the row boundary. Use FLASH_PageAddressGet() to obtain the starting address of the row.

• nvm_status_t CONFIGURATION_RowWrite (configuration_address_t address, configuration_data_t *dataBuffer)

  Writes all the Configuration Words. The size of the buffer must be one Configuration row/sector and the address must be aligned with the row boundary (the first Configuration word location). Use FLASH_PageAddressGet() to obtain the starting address of the row.
