Function Documentation

void halInternalGetMfgTokenData	(	void *	data,
		int16u	token,
		int8u	index,
		int8u	len
	)

Copies the token value from non-volatile storage into a RAM location.

This is the internal function that the exposed API (halCommonGetMfgToken) expands out to. The API simplifies the access into this function by hiding the size parameter.

Parameters:

	data,:	A pointer to where the data being read should be placed.
	token,:	The name of the token to get data from. On this platform that name is defined as an address.
	index,:	The index to access. If the token being accessed is not an indexed token, this parameter is set by the API to be 0x7F.
	len,:	The length of the token being worked on. This value is automatically set by the API to be the size of the token.

void halInternalSetMfgTokenData	(	int16u	token,
		void *	data,
		int8u	len
	)

Sets the value of a token in non-volatile storage.

This is the internal function that the exposed API (halCommonSetMfgToken) expands out to. The API simplifies the access into this function by hiding the size parameter.

NOTE: CIB manufacturing tokens can only be written by on-chip code if the token is currently unprogrammed.

REMEMBER: The flash hardware requires writing to 16bit aligned addresses with a length that is multiples of 16bits.

Parameters:

	token,:	The name of the token to get data from. On this platform that name is defined as an address.
	data,:	A pointer to the data being written.
	len,:	The length of the token being worked on. This value is automatically set by the API to be the size of the token.
