DFIOMapSpace

This is a helper function to allow easy access to external memory/chip-selects, when using Trizeps6 with onboard WLAN (when the WLAN-chip is configured to use D[15..8]).

void* DFIOMapSpace(      
  unsigned int physbase,
  unsigned int length,
  unsigned int* csbase
); 

physbase
Physical address of the external memory-space to map.

length
Length of memory-space to map.

csbase
Pointer to an unsigned int, which will receive a value needed by DFIORead and DFIOWrite.

The return-value is virtual address of the mapped address-space.

If the function fails, the return value is NULL.

You should not use the mapped address-space directly. Instead use DFIOWrite and DFIORead.
