 *                We add this function to force users to set rf cal sector, since
 *                we don't know which sector is free in user's application.
 *                sector map for last several sectors : ABBBCDDD
 *                A : rf cal
 *                B : at parameters
 *                C : rf init data
 *                D : sdk parameters
 * Parameters   : none
