lets have a page with all of the testpoints
== General ==
The Wii U motherboard exposes several test points, primarily on the bottom of the motherboard (CPU heatsink facing down).

== EXI0 ==
* TP101 - CLK
* TP176 - MISO (Device out, Wii U in)
* Test point between TP100 and TP176 - MOSI (Device in, Wii U out)

== DEBUG ==
These pins are set to various 8-bit values to indicate the current stage of [[boot0]].

* TP50 - DEBUG0
* TP51 - DEBUG1
* TP52 - DEBUG2
* TP53 - DEBUG3
* TP55 - DEBUG4
* TP54 - DEBUG5
* TP48 - DEBUG6
* TP49 - DEBUG7

== Misc/Unk ==
* TP102 - Not EXI0?
* TP144 - Reset? Or functions like one when pulled down by a 3.3Kohm resistor.
* TP127 - ARM/IOP power rail?
