  * RSIP(OTF) Introduction
  *****************************************************************************************
  *		-used for flash firmware protection, and flash firmware will be encrypted use AES.
  *		-16B KEY shoud be written to EFUSE OTP KEY area use EFUSE_OTF_KEY.
  *		-Enable should be write to EFUSE 0x19[5].
  *****************************************************************************************
  * RDP Introduction
  *****************************************************************************************
  *		-after enable RDP, top 4k RAM can not be read.
  *		-16B RDP key should be written to EFUSE RDP key area use EFUSE_RDP_KEY.
  *		-Enable bit should be write to EFUSE use EFUSE_RDP_EN.
