functions. The first ten are for time and date information. The next four (0Ah to 0Dh) are registers,
which configure and report RTC functions.

8.13 GPIO

Various general purpose inputs and outputs are provided for custom system design. The number of
inputs and outputs varies depending on C200 series configuration.

8.14 Enhanced Power Management

The C200 series power management functions include enhanced clock control and various low-power
(suspend) states (for example, Suspend-to-RAM and Suspend-to-Disk). A hardware-based thermal
management circuit permits software-independent entrance to low-power states. The chipset
contains full support for the Advanced Configuration and Power Interface (ACPI) Specification,
Revision 3.0a.

8.15 System Management Features

In addition to Intel AMT, the C200 series chipset integrates several functions designed to manage the
system and lower the total cost of ownership (TCO) of the system. These system management
functions are designed to report errors, diagnose the system, and recover from system lockups
without the aid of an external microcontroller.
8.15.1

TCO Timer

The chipset's integrated programmable TCO timer is used to detect system locks. The first expiration
of the timer generates an SMI# that the system can use to recover from a software lock. The second
expiration of the timer causes a system reset to recover from a hardware lock.
8.15.2

Processor Present Indicator

The chipset looks for the processor to fetch the first instruction after reset. If the processor does not
fetch the first instruction, the Ibex Peak will reboot the system.
8.15.3

Error Code Correction (ECC) Reporting

When detecting an ECC error, the host controller has the ability to send one of several messages to
the chipset. The host controller can instruct the chipset to generate an SMI#, NMI, SERR#, or TCO
interrupt.
8.15.4

Function Disable

The chipset provides the ability to disable the following integrated functions: LAN, USB, LPC, Intel
HD Audio, SATA, PCI Express or SMBus. Once disabled, these functions no longer decode I/O, memory,
or PCI configuration space. Also, no interrupts or power management events are generated from the
disabled functions.
8.15.5

Intruder Detect

The chipset provides an input signal (INTRUDER#) that can be attached to a switch that is activated
when the system case is opened. The chipset can be programmed to generate an SMI# or TCO
interrupt due to an active INTRUDER# signal.
