This describes the process of booting to SCI without having to change the corresponding switches on a controlCARD. This can enable easier flash programming through SCI. The following modifications can be added into User OTP or Flash, both methods will be described here. The modified boot process will boot to this code on Reset, and determine if SCI is being used or not. If SCI is inactive, it will branch to user AppCode.
