8.4.3. Pentium Pro Processor Time-Out Counter
The Pentium Pro processor implements a time-out counter, which issues a fatal error if the pro-
cessor is stalled for a long period of time. This mechanism is not related to the Pentium Pro pro-
cessor bus time-out errors described in Section 8.2.4., "Time-out Errors". The timer is 31 bits
wide and is clocked from BCLK. The processor is not considered stalled when in normal modes
(e.g. Stopclock or HALT).
