Initial settings for SH7786 PCI Express

Posted: 07 Sep 2011 ?? ?Print Version ?Bookmark and Share

Keywords:PCI Express? controller? initial settings?

The PCI Express controller (PCIEC) initialization sample program presented in this application note makes initial settings to the local bus state controller (LBSC), DDR3-SDRAM interface (DBSC3), and PCIEC after the power-on reset is cleared. After initialization, the PCI Express controller (PCIEC) operates either as a PCI Express root port or endpoint. When operating as a PCI Express root port, it displays on the serial console information such as the vendor ID and device ID of PCI Express endpoint devices and executes simple DMA transfers. When operating as a PCI Express endpoint, it specifies setting items such as vendor ID and device ID in the PCIEC.
