Thermal Specifications

6.2.2.1

Frequency/VID Control

When the Digital Temperature Sensor (DTS) reaches a value of 0 (DTS temperatures

reported via PECI may not equal zero when PROCHOT# is activated, see

Section 6.3

for

further details), the TCC will be activated and the PROCHOT# signal will be asserted.

This indicates the processors' temperature has met or exceeded the factory calibrated

trip temperature and it will take action to reduce the temperature.

Upon activation of the TCC, the processor will stop the core clocks, reduce the core

ratio multiplier by 1 ratio and restart the clocks. All processor activity stops during this

frequency transition which occurs within 2 us. Once the clocks have been restarted at

the new lower frequency, processor activity resumes while the voltage requested by the

VID lines is stepped down to the minimum possible for the particular frequency.

Running the processor at the lower frequency and voltage will reduce power

consumption and should allow the processor to cool off. If after 1ms the processor is

still too hot (the temperature has not dropped below the TCC activation point, DTS

still = 0 and PROCHOT is still active) then a second frequency and voltage transition will

take place. This sequence of temperature checking and Frequency/VID reduction will

continue until either the minimum frequency has been reached or the processor

temperature has dropped below the TCC activation point.

If the processor temperature remains above the TCC activation point even after the

minimum frequency has been reached, then clock modulation (described below) at that

minimum frequency will be initiated.

There is no end user software or hardware mechanism to initiate this automated TCC

activation behavior.

A small amount of hysteresis has been included to prevent rapid active/inactive

transitions of the TCC when the processor temperature is near the TCC activation

temperature. Once the temperature has dropped below the trip temperature, and the

hysteresis timer has expired, the operating frequency and voltage transition back to

the normal system operating point via the intermediate VID/frequency points.

Transition of the VID code will occur first, to insure proper operation as the frequency is

increased. Refer to

Table 6-3

for an illustration of this ordering.
