* @n@b TCP2_tailConfigIs2000
*
* @b Description
* @n This function generates the input control values IC6-IC11 for IS2000
* channels. These values consist of the tail data following the
* systematics and parities data. This function is called from the generic
* TCP2_tailConfig function.
*
* @b Arguments
@verbatim
mode TCP processing mode (SA or SP)
map TCP shared processing MAP
rate TCP data code rate
tailData Pointer to the tail data
configIc Pointer to the IC values structure
@endverbatim
*
* <b> Return Value </b>
* @n None
*
* <b> Pre Condition </b>
* @n None
*
* <b> Post Condition </b>
* @n The configIc structure is assigned the tail configuration values
* based on the taildata.
*
* @b Modifies
* @n The configIc argument passed.
*
* @b Example
* @verbatim
extern TCP2_Params *configParms;
TCP2_ConfigIc *configIc;
TCP2_UserData *xabData = &userData[frameLen];
...
TCP2_tailConfigIs2000 (configParms->mode, configParms->map,
configParms->rate,
userData, configIc);
