 This switch is handy when in trace mode and you're constantly getting the pc moving away from your current code due to interrupts.
+===== Switch 8 - Dummy 8KB cartridge =====

+> Fourth, the Nexys4DDR boards thought that they always had an 8KB cartridge plugged in if switch 8 was not set.  This was a debug thing I put in when getting the cartridge interface to work some time ago, and of course then promptly forgot about, resulting in a few hours of lost time trying to figure out why on earth I was seeing 30719 BYTES FREE, but no actual data in the mapped cartridge.

 ===== Switch 12 - Hypervisor debug output =====
+__NOTE__: (18/02/2018) Switch 12 is no longer used for the hypervisor debug output. It is now triggered via the Shift key on the USB keyboard attached to the hardware.
 This switch decides whether Hypervisor debug output will be shown (via the remote serial monitor output) or not.
