6. Customizing the software

The software architecture supports PCI and GPIO modes. In PCI and GPIO modes, read
and write registers of the ISP176x can be memory mapped. You can configure the
interrupt for the ISP176x as either edge-triggered or level-triggered using the Hardware
Mode Control register. To customize the ISP176x, refer to the ISP176xHCDConfig.h file,
located under the ‘WINCE500\3rdparty\ST-ERICSSON\phISP176xHCD\phISP176xCOM’
directory.
