LEFT

LEFT is one of the six types of ports of a node. The left port will send communication to the node adjacently left of the current node.
== Description ==
The four communication registers UP, DOWN, LEFT, and RIGHT correspond to the four ports that all Basic Execution Nodes use to communicate with topologically adjacent nodes. Some ports will be disconnected on certain nodes within the hardware, and will block indefinitely if a READ or WRITE command is issued. Refer to the interconnection diagram for the node to determine which ports are available for use.
