6522: can CAx and CBx used as inputs?

Hallo allemaal,


I'm reviving some old projects with their own PCBs and I need some extra 
inputs to read some DIP switches. I have a 6522 and its CAx and CBx pins 
are not used so the idea rose to use them. But I never ever used them as 
inputs myself before and studying the data sheets, I came to the 
conclusion that these these pins can only be used as inputs to generate 
an interrupt and cannot be read like one of the PAx or PBx pins. That 
would a bit of a bummer so I hope I'm wrong.

Can anybody confirm my conclusion, or better, tell me that I'm wrong?

Thank you very much in advance!
