Portsdown 4 /Langstone build bandswitching

Hi all,
Combined build is progressing slowly but I've now got a question. This is probably very obvious but I'm possibly confusing myself. On the GPIO there is the Portsdown D0, D1 and D2, there is also the Langstone D0-D7 (some shared). I'm hoping to use a BATC 8 way switch, do I use the Portsdown data bit pins and simply map the Langstone "band bits" to give a comparable output? Hopefully someone has done this already and can point me in the right direction.
73 Dave.

Hi Dave

Yes, just use the Portsdown D0, D1 and D2 Band bits, and set the Langstone to give the right patterns on those bits. The extra Langstone bits are there to allow the use of non-BATC switching boards.

Thanks Dave

That makes sense.
