Macros
#define	CLASSB_CRC_USE_HW
	Compile hardware implementation.
#define	CLASSB_CRC_USE_SW
	Compile software implementation.
#define	CLASSB_CRC_16_BIT
	Compile 16-bit functions.
#define	CLASSB_CRC_32_BIT

Typedefs
typedef uint32_t	crcbytenum_t
	Data type to use for byte counts in CRC computations. This type should be kept as small as possible to optimize for speed.
typedef uint32_t	flash_addr_t
	Data type for holding flash memory addresses. Depending of the size of the device it will be necessary to use 32 or 16 bits.
typedef const void *	eepromptr_t
	Generic pointer to EEPROM.
typedef const uint8_t *	eeprom_uint8ptr_t
	Pointer to a byte in EEPROM.
typedef const uint16_t *	eeprom_uint16ptr_t
	Pointer to two bytes in EEPROM.
typedef const uint32_t *	eeprom_uint32ptr_t
	Pointer to four bytes in EEPROM.
typedef flash_addr_t	flashptr_t
	Generic pointer to Flash.
typedef flash_addr_t	flash_uint8ptr_t
	Pointer to a byte in Flash.
