Re: In Harmony V3, what function is for unlock sequence ?
Thank you very much for kind advice. 4 days has passed, after I posted this thread. It seems that you are right.
So for the moment at least I use below, which is a little bit "clumsy" but works well as unlock/lock sequence for PIC32MZ.
SYSKEY = 0;
SYSKEY = 0xAA996655; // Write Key1 to SYSKEY
SYSKEY = 0x556699AA; // Write Key2 to SYSKEY
SYSKEY = 0x33333333;
