	* (1 << (arg_FieldMSBBit + 1 - arg_FieldLSBBit)) - 1.
	* @Param: - IN arg_FieldLSBBit an unsigned integer value representing the position of the least significant
	* bit of the bit field.
	* @Param: - IN arg_FieldMSBBit an unsigned integer value representing the position of the most significant
	* bit of the bit field.
	*
	* @Return: Returns the updated value of arg_PackedData32.
