4.10.2.1. Using Direct User Avalon-MM Interface (Byte Access)
Targeting PF Configuration Space Registers
User application needs to specify the offsets of the targeted PF registers.
For example, if the application wants to read the MSI Capability Register of PF0, it will issue a Read with address 0x0050 to target the MSI Capability Structure of PF0.
Targeting VSEC Registers
User application needs to program the VSEC field (0x104068 bit[0]) first. Then all accesses from the user Avalon® -MM interface starting at offset 0xD00 will be translated to VSEC configuration space registers.
