6025E Register Map: where are the 82C55 Ports?

[spg]

Hi,

I have written a driver for 6024E, and now would like to add support for the additional I/O ports available on 6025E. However, I can't seem to figure out the address to access these ports, and don't see any reference to these within the DDK files.

Any help would be appreciated -- thanks!

ok, I finally found this in comedi driver source:

#define Port_A 0x19
#define Port_B 0x1b
#define Port_C 0x1d
#define Configuration 0x1f

It must be in the NI docs somewhere, but for the life of me I can't find it.
