Theory of Operation—Intel ® 945GME Express Chipset
3.4.2.11 Clocks
The Intel ® 945GME Express Chipset board uses a CK-410M and CK-SSCD compatible
solution. The CK-SSCD solution offers improved EMI performance by spreading the
radiated clock emissions over a wider spectrum than a single frequency. This is
accomplished while controlling the clock frequency deviation such that system
performance is not compromised. The FSB frequency is determined from decoding the
processor BSEL[2:0] pin settings.
3.4.2.12 Real Time Clock
An on-board battery at BT5H1 maintains power to the real time clock (RTC) when in a
mechanical off state. A CR2032 battery is installed on the Intel ® 945GME Express
Chipset development kit.
3.4.2.13 Thermal Monitoring
The processor has a thermal diode for temperature monitoring. The SMC thermal
monitoring device will throttle the processor if it becomes hot. If the temperature of the
processor rises too high, the SMC will alternately blink the CAPS lock and NUM lock
LEDs on the board, and the board will shut down.
3.4.3 System I/O and Connector Summary
