<p>core 3.0 changes/refresh</p> <p><b>New page</b></p><div>{{NextRegister<br /> |Number=$63<br /> |Readable=No<br /> |Writable=Yes<br /> |ShortDesc=Used to upload code to the [[Copper]].<br /> }}<br /> Similar to {{NextRegNo|$60}}, allows to upload Copper instructions to the copper memory, but the difference is that writes are committed to copper memory in 16-bit words (only half-written instructions by using NextReg $60 may get executed, $63 prevents that).<br /> <br /> The first write to this register is MSB of Copper Instruction destined for even copper instruction address.<br /> <br /> The second write to this register is LSB of Copper Instruction destined for odd copper instruction address.<br /> <br /> After any write, the copper address is auto-incremented to the next memory position.<br /> <br /> After a write to an odd address, the entire 16-bits are written to Copper memory at once.</div>
