Can we get a memory word/variable which we can write to but which gets cleared when the FEE is powered off/reset?</p> <p>I don't think there is anything in place now. I could use one of the existing non-persistent voltages, but that feels wrong.</p> INSTRM-118

Add writable variable which is cleared on power-cycle

Umm,</p> <p>Non-volatile:</p> <ul> <li>Fetch with: <tt>~gI</tt></li> <li>Set with: <tt>~sI,N</tt> N=1..254</li> <li>255 is what the burner leaves in memory, indicating that the firmware, etc. have not been initialized.</li> <li>0 is what the firmware set when it has configured itself.</li> </ul> <p>Volatile:</p> <ul> <li>Fetch with <tt>~gRS</tt></li> <li>Set with <tt>~sRS,CCCCCCCC</tt> where <tt>CCCCCCCC</tt> is a 32-bit hex number.</li> <li>0 on power-up, power-cycle, reboot, reset.</li> </ul> <p>Work has been done.<br/> Not used anywhere yet though.</p> Development Rank 0|ii023r:
