Detailed Description

Function Documentation

uint32_t CRC32_getResult

(

uint8_t

crcMode

)

Returns the value of the signature result.

This function returns the value of the signature result generated by the CRC32. Bit 0 is treated as LSB.

Parameters

crcMode

selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

The signature result

uint32_t CRC32_getResultReversed

(

uint8_t

crcMode

)

Returns the bit-wise reversed format of the 32 bit signature result.

This function returns the bit-wise reversed format of the signature result. Bit 0 is treated as MSB.

Parameters

crcMode

selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

The bit-wise reversed format of the signature result

void CRC32_set16BitData	(	uint16_t	dataIn,
		uint8_t	crcMode
	)

Sets the 16 bit data to add into the CRC32 module to generate a new signature.

This function sets the given data into the CRC32 module to generate the new signature from the current signature and new data. Bit 0 is treated as the LSB.

Parameters

dataIn	is the data to be added, through the CRC32 module, to the signature.
crcMode	selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

None

void CRC32_set16BitDataReversed	(	uint16_t	dataIn,
		uint8_t	crcMode
	)

Translates the data by reversing the bits in each 16 bit data and then sets this data to add into the CRC32 module to generate a new signature.

This function first reverses the bits in each byte of the data and then generates the new signature from the current signature and new translated data. Bit 0 is treated as the MSB.

Parameters

dataIn	is the data to be added, through the CRC32 module, to the signature.
crcMode	selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

None

void CRC32_set32BitData

(

uint32_t

dataIn

)

Sets the 32 bit data to add into the CRC32 module to generate a new signature.

This function sets the given data into the CRC32 module to generate the new signature from the current signature and new data. Bit 0 is treated as the LSB.

Parameters

dataIn

is the data to be added, through the CRC32 module, to the signature.

Returns

None

void CRC32_set32BitDataReversed

(

uint32_t

dataIn

)

Translates the data by reversing the bits in each 32 bit data and then sets this data to add into the CRC32 module to generate a new signature.

This function first reverses the bits in each byte of the data and then generates the new signature from the current signature and new translated data. Bit 0 is treated as the MSB.

Parameters

dataIn

is the data to be added, through the CRC32 module, to the signature.

Returns

void CRC32_set8BitData	(	uint8_t	dataIn,
		uint8_t	crcMode
	)

Sets the 8 bit data to add into the CRC32 module to generate a new signature.

This function sets the given data into the CRC32 module to generate the new signature from the current signature and new data. Bit 0 is treated as the LSB.

Parameters

crcMode	selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

None

void CRC32_set8BitDataReversed	(	uint8_t	dataIn,
		uint8_t	crcMode
	)

Translates the data by reversing the bits in each 8 bit data and then sets this data to add into the CRC32 module to generate a new signature.

This function first reverses the bits in each byte of the data and then generates the new signature from the current signature and new translated data. Bit 0 is treated as the MSB.

Parameters

dataIn	is the data to be added, through the CRC32 module, to the signature.
crcMode	selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

None

void CRC32_setSeed	(	uint32_t	seed,
		uint8_t	crcMode
	)

Sets the seed for the CRC32.

This function sets the seed for the CRC32 to begin generating a signature with the given seed and all passed data. Using this function resets the CRC32 signature.

Parameters

seed	is the seed for the CRC32 to start generating a signature from. Modified bits are CRC32INIRESL0 of CRC32INIRESL0 register.
crcMode	selects the mode of operation for the CRC32 Valid values are: CRC32_MODE - 32 Bit Mode CRC16_MODE - 16 Bit Mode

Returns

None
