It's a 32-bit value referencing the 28 GPIO pins on the SA1100/1110. The 
masking of these bits depends on how the particular implementation chose to 
wire the signals to PCMCIA signals; the GPIO bits are as the name implies 
"general purpose" and not specifically dedicated to PCMCIA functions.

On the 7312 the bits you need will be in the PORTA,B,C,D,E registers. (I 
have the EDB7209 with 7212 on it, no PS6700, so I don't know how Cirrus 
wired it).
