Special Logical Device Configuration Registers 3.2.4 Standard Configuration Registers Figure 4. Configuration Register Map ServerI/O Control and Configuration Registers The ServerI/O configuration registers at indexes 20h (ServerI/O ID) and 27h (ServerI/O Revision ID) are used for part iden- tification. The other configuration registers are used for global power management and selecting pin multiplexing options. For details, see Section 3.7 on page 48. Logical Device Control and Configuration Registers A subset of these registers is implemented for each logical device. See functional block descriptions in the following sections. Index Register Name Description F0h-FEh Logical Device Configuration Special (vendor-defined) configuration options. ServerI/O Control and Configuration Registers Logical Device Control and one per Logical Device Configuration Registers - Index Register Name 07h Logical Device Number 20h ServerI/O ID 21h ServerI/O Configuration 1 22h ServerI/O Configuration 2 23h ServerI/O Configuration 3 24h ServerI/O Configuration 4 25h ServerI/O Configuration 5 26h ServerI/O Configuration 6 27h ServerI/O Revision ID 28h ServerI/O Configuration 8 29h Clock Generator Configuration 2Ah ACCESS.bus Configuration 2Bh - 2Fh Reserved for National use 30h Logical Device Control (Activate) 60h I/O Base Address Descriptor 0 Bits 15-8 61h I/O Base Address Descriptor 0 Bits 7-0 62h I/O Base Address Descriptor 1 Bits 15-8 63h I/O Base Address Descriptor 1 Bits 7-0 70h Interrupt Number and Wake-Up on IRQ Enable 71h IRQ Type Select 74h DMA Channel Select 0 75h DMA Channel Select 1 F0h - FFh Device Specific Logical Device Configuration (some are optional) |
