Hello, It seems like you want to use external interface on the module through the Auxiliary I/O Bus?

By using WrPortI() you can set the internal registers.
For more information on this please check Dynamic C function reference manual.

And also check processor reference manual to know more about what are the steps you need to follow to use Auxiliary I/O Bus.

Thanks.

Is the following command correct?
WrPortI(IB2CR,&IB2CRShadow,0x82);
—for setting up I/O bank 2?

Actually this register is ,to set wait state and read or write strobe.
Please check the processor’s reference manual page 263 for more info on the IB2CR bits.
