Software Programming Model
This section describes the software programming model for the CompactFlash core.
HAL System Library Support
The Altera-provided HAL API functions include a device driver that you can use to initialize the
CompactFlash core. To perform other operations, use the low-level macros provided.
For more information on the macros, refer to the Software Files section.
Software Files
The CompactFlash core provides the following software files. These files define the low-level access to the
hardware. Application developers should not modify these files.
