Detailed Description

Function Documentation

uint16_t CRC_getData

(

uint16_t

baseAddress

)

Returns the value currently in the Data register.

This function returns the value currently in the data register. If set in byte bits reversed format, then the translated data would be returned.

Parameters

baseAddress

is the base address of the CRC module.

Returns

The value currently in the data register

uint16_t CRC_getResult

(

uint16_t

baseAddress

)

Returns the value pf the Signature Result.

This function returns the value of the signature result generated by the CRC.

Parameters

baseAddress

is the base address of the CRC module.

Returns

The value currently in the data register

uint16_t CRC_getResultBitsReversed

(

uint16_t

baseAddress

)

Returns the bit-wise reversed format of the Signature Result.

This function returns the bit-wise reversed format of the Signature Result.

Parameters

baseAddress

is the base address of the CRC module.

Returns

The bit-wise reversed format of the Signature Result

void CRC_set16BitData	(	uint16_t	baseAddress,
		uint16_t	dataIn
	)

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

This function sets the given data into the CRC module to generate the new signature from the current signature and new data.

Parameters

baseAddress	is the base address of the CRC module.
dataIn	is the data to be added, through the CRC module, to the signature. Modified bits are CRCDI of CRCDI register.

Returns

None

void CRC_set16BitDataReversed	(	uint16_t	baseAddress,
		uint16_t	dataIn
	)

Translates the 16 bit data by reversing the bits in each byte and then sets this data to add into the CRC 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.

Parameters

baseAddress	is the base address of the CRC module.
dataIn	is the data to be added, through the CRC module, to the signature. Modified bits are CRCDIRB of CRCDIRB register.

Returns

None

void CRC_set8BitData	(	uint16_t	baseAddress,
		uint8_t	dataIn
	)

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

This function sets the given data into the CRC module to generate the new signature from the current signature and new data.

Parameters

baseAddress	is the base address of the CRC module.
dataIn	is the data to be added, through the CRC module, to the signature. Modified bits are CRCDI of CRCDI register.

Returns

None

void CRC_set8BitDataReversed	(	uint16_t	baseAddress,
		uint8_t	dataIn
	)

Translates the 8 bit data by reversing the bits in each byte and then sets this data to add into the CRC 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.

Parameters

baseAddress	is the base address of the CRC module.
dataIn	is the data to be added, through the CRC module, to the signature. Modified bits are CRCDIRB of CRCDIRB register.

Returns

None

void CRC_setSeed	(	uint16_t	baseAddress,
		uint16_t	seed
	)

Sets the seed for the CRC.

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

Parameters

baseAddress	is the base address of the CRC module.
seed	is the seed for the CRC to start generating a signature from. Modified bits are CRCINIRES of CRCINIRES register.

Returns

None
