1. The board will return “0” for all address that are not used.
The APC8640 base addresses are determined through the
PCI Configuration Registers. The addresses given in the
memory map are relative to the base addresses (PCIBar2,
PCIBar3) of the APC8640 carrier as shown in Table 3.2. The
addresses within each IP’s own space are specific to that IP
module. Refer to the IP module’s User Manual for information
relating to the IP specific addressing.
The Carrier registers, IP Identification (ID) spaces, IP
Input/Output (IO), IP Interrupt spaces, and Memory (MEM)
spaces are accessible via the PCI bus space as given in Tables
3.3. A 32-bit PCI bus access will result in two 16-bit accesses to
the IP module. A 16-bit or 8-bit PCI bus access results in a
single 16-bit or 8-bit access to the IP module respectively.
Carrier Status/Control Register - (Read/Write, P 00H)
The Carrier Board Status Register reflects and controls
functions globally on the carrier board. This includes monitoring
the IP Error signal, enabling, disabling, or monitoring IP and
timeout interrupts, performing a software reset including the
carrier and IP modules, and identifying if memory space is
enabled.
