Intel PCI-X user manual

GigMAC-PMC and PCI
GigPMC Switch	Board and Driver Users Manual

Functions to read and write registers in the switch:

STATUS inReadSpiReg(int unit, int page, int offset, int bCnt, UINT8 *pData); STATUS inWriteSpiReg8(int unit, int page, int offset, int val);

STATUS inWriteSpiReg16(int unit, int page, int offset, int val);

STATUS inWriteSpiReg32(int unit, int page, int offset, int val);

Note: The Intel device driver supporting the Model 5468/6468 cards initializes the switch by writing a default configuration during initialization. This is performed in the Intel driver initialization using the function “inLiInitBcm5388()”. This function may be modified to make changes to the default configuration. Additional switch management functions may be implemented using the low-level register access API shown. For additional information and register programming details, please contact technical support.
