82801CA Datasheet, PDF (30/521 Pages) Intel Corporation – I/O Controller Hub 3-S (ICH3-S)

Introduction
Chapter 7. LAN Controller Registers
Chapter 7 provides a detailed description of all registers that reside in the ICH3’s integrated LAN
Controller. The integrated LAN Controller resides on the ICH3’s external PCI bus (typically Bus 1)
at Device 8, Function 0 (B1:D8:F0).
Chapter 8. Hub Interface to PCI Bridge Registers
Chapter 8 provides a detailed description of all registers that reside in the Hub Interface to PCI
bridge. This bridge resides at Device 30, Function 0 (D30:F0).
Chapter 9. LPC Bridge Registers
Chapter 9 provides a detailed description of all registers that reside in the LPC bridge. This bridge
resides at Device 31, Function 0 (D31:F0). This function contains registers for many different units
within the ICH3 including DMA, Timers, Interrupts, CPU Interface, GPIO, Power Management,
System Management and RTC.
Chapter 10. IDE Controller Registers
Chapter 10 provides a detailed description of all registers that reside in the IDE controller. This
controller resides at Device 31, Function 1 (D31:F1).
Chapter 11. USB 1.1 Controller Registers
Chapter 11 provides a detailed description of all registers that reside in the three UHCI host
controllers. These controllers reside at Device 29, Functions 0, 1 and 2 (D29:F0/F1/F2).
Chapter 12. SMBus Controller Registers
Chapter 12 provides a detailed description of all registers that reside in the SMBus controller. This
controller resides at Device 31, Function 3 (D31:F3).
Chapter 13. AC ’97 Audio Controller Registers
Chapter 13 provides a detailed description of all registers that reside in the audio controller. This
controller resides at Device 31, Function 5 (D31:F5). Note that this section of the datasheet does
not include the native audio mixer registers. Accesses to the mixer registers are forwarded over the
AC-link to the codec where the registers reside.
Chapter 14. AC ’97 Modem Controller Registers
Chapter 14 provides a detailed description of all registers that reside in the modem controller. This
controller resides at Device 31, Function 6 (D31:F6). Note that this section of the datasheet does
not include the modem mixer registers. Accesses to the mixer registers are forwarded over the AC-
link to the codec where the registers reside.
Chapter 15. Pinout Definition
Chapter 15 provides a table of each signal and its ball assignment in the 421 BGA package.
Chapter 16. Electrical Characteristics
Chapter 16 provides all AC and DC characteristics including detailed timing diagrams.
Chapter 17. Package Information
Chapter 17 provides drawings of the physical dimensions and characteristics of the 421 BGA
package.
Chapter 18. Testability
Chapter 18 provides details about the implementation of test modes provided in the ICH3.
