    3.2 The I/O Address Map The list of PCI-1002 registers is given below. The address of each register is found by simply adding the offset to the base address of the corresponding section. More detailed descriptions of each register will be shown in the following text and the software manual.
  • Page 27 3.2.1 Section 1 Although there are 128 I/O ports used by the on-board PCI interface controller, only one register is used in real applications!! Users should keep the other registers from being modified! The PCI interrupt control register (4Ch) controls the interrupt sent to your system.
