Neil,
Is there a specific set of registers you need to access ?
The hybrid Peter/Tank module lets you access all the control registers
in the physical range 0x48002030-0x48002264 and 0x480025A0-0x480025A0
and if the IO pin you need to access doesn't have a GPIO in mode 4, I
can add them to the "safe" range for you. I have added all the pins
that go to the Expansion and the Auxiliary connectors, so the pin you
are trying to access will have no "exit" from the board, unless you
wish to use the LCD connector outputs as well!!
