<li>m3 bit 6: the entrance and/or exit signals on this tile are restricted (tracerestrict patch)</li>
<li>m3 bits 5..3: entrance signal aspect (only valid if signal is present and not red, and multi-aspect signalling is in effect)</li>
<li>m3 bits 2..0: exit signal aspect (only valid if signal is present and not red, and multi-aspect signalling is in effect)</li>
<li>m6 bit 7: set = exit signal shows green, clear = exit signal shows red</li>
