DFIORead

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]).

short DFIORead(      
  volatile short* addr,
  unsigned int csbase,
); 

addr
address, within the address-range previously mapped with DFIOMapSpace.
csbase
csbase value returned by DFIOMapSpace.

Returns value read from specified address.

This routine can be used with all Trizeps6-modules. Even with ones without WLAN, where this function is not necessary and you can read the address directly.

OS Versions: Windows Embedded CE 6 and later.
Header: drvlib_app.h.
Link Library: drvlib_app.lib.
