Wire node

This code from block 882 is loaded into node 614. It is typical of code for wire nodes; nodes that merely pass data from one port to another. Such nodes typically have a low duty cycle and use little power. But they're essential to connect nodes that have constrained positions, such as a/d nodes.

Often such nodes can operate on the data passing thru, providing a service and adding to useful cpu cycles.

Different versions of this code only require changing the comments, register addresses and loading path. Actually everything except go.

go

An infinite loop that reads from the port addressed by register b and writes to the port addressed by register a. It uses one word of RAM and requires an instruction fetch for each transfer, but the code is simple and transparent.
