Macros
NVM Commands
NVMcommands related to 32-bit CRC for flash memory. This is only used by CLASSB_CRC32_Flash_HW.
#define	CRC_FLASH_RANGE   NVM_CMD_FLASH_RANGE_CRC_gc
	Compute a CRC checksum on an address range.
#define	CRC_BOOT   NVM_CMD_BOOT_CRC_gc
	Compute a CRC checksum on the application section.
#define	CRC_APP   NVM_CMD_APP_CRC_gc
	Compute a CRC checksum on the boot section.

Functions
CRC tests
Invariant memory tests based on CRC that are compliant with IEC60730 Class B.
uint16_t	CLASSB_CRC16_EEPROM_HW (eepromptr_t dataptr, const crcbytenum_t numBytes, eeprom_uint16ptr_t pchecksum)
	Compute 16-bit CRC for EEPROM address range using hardware CRC module.
uint16_t	CLASSB_CRC16_Flash_HW (flashptr_t dataptr, const crcbytenum_t numBytes, eeprom_uint16ptr_t pchecksum)
	Compute 16-bit CRC for Flash address range using hardware CRC module.
uint32_t	CLASSB_CRC32_EEPROM_HW (eepromptr_t dataptr, const crcbytenum_t numBytes, eeprom_uint32ptr_t pchecksum)
	Compute 32-bit CRC for EEPROM address range using hardware CRC module.
uint32_t	CLASSB_CRC32_Flash_HW (NVM_CMD_t crc_type, flashptr_t dataptr, const crcbytenum_t numBytes, eeprom_uint32ptr_t pchecksum)
	Compute 32-bit CRC for Flash address range using hardware CRC module.
