[ts-7000] TS7400- How to read DIO pins

["gnloch" <>]

Hi all...

I trying to make a module, which can read and write in DIO pins.
The write function is working properly. I write using writeb(), 0xff on 
0x12c00000 address, the I write on th DIO pin
But I can't read from any DIO pin using readb();
Anybody knows how to read the DIO pins?

thx

Günter
