Programming - GE PCIE-5565PIORC* Hardware Reference Manual

3 • Programming
Basic target write and read operations of the RFM‐5565 require little or no
software. The board powers up in a functional mode. The user will need to access
the PCI Configuration registers (Base Address Register 0, 1, 2 and 3) to learn
where the system BIOS has located the other register sets and the Reflective
Memory.
The location of the register sets and the Reflective Memory varies from system to
system, and can even vary from slot to slot within a system. For operations
beyond the basic setup, such as enabling or disabling interrupts or performing
DMA cycles, the user must know the specific bit assignments of the registers
within the three register sets. That information is provided in this chapter.
The three register sets are:
• PCI Configuration Registers
• Local Configuration Registers
• RFM Control and Status Registers
