I managed to get some samples out of Eurodis UK, but it was quite difficult
(several emails and phone calls). Silica UK then sold me 20 chips but most
distributors will only sell them by the tray (250 pcs), and they are on 6-8
weeks delivery.

I use pins 1,2,3,4, 47 and 48 - works fine with the Wiggler and both the
OCDemon software and the RAL debugger.

The Wiggler interface is supported by the RAL software I use.

Sorry, delete pin 4!

You need nTRST.
