• PCMCIA Port 0 starts at 0x30000000
• PCMCIA Port 1 starts at 0x40000000

Offset	Content
+0x00000000	64MB PCMCIA Attributes
+0x04000000	64MB PCMCIA I/O Space
+0x08000000	64MB PCMCIA Memory Space
+0x0C000000	64MB PCMCIA Control

Memory and attribute space is 16 bits wide, I/O space is 8 or 16 bits wide, depending on the state of ~IOIS16. The controller can simulate 32 bit access.
