PROCHOT# Signal

The PROCHOT# (processor hot) signal is asserted by the processor when the TCC is active. Only a single PROCHOT# pin exists at a package level. When any DTS temperature reaches the TCC activation temperature, the PROCHOT# signal will be asserted. PROCHOT# assertion policies are independent of Adaptive Thermal Monitor enabling.

The PROCHOT# signal can be configured to the following modes:

  • Input Only: PROCHOT is driven by an external device.
  • Output Only: PROCHOT is driven by processor.
  • Bi-Directional: Both Processor and external device can drive PROCHOT signal

PROCHOT Input Only

The PROCHOT# signal should be set to input only by default. In this state, the processor will only monitor PROCHOT# assertions and respond by setting the maximum frequency to 10Khz.

The following two features are enabled when PROCHOT is set to Input only:

  • Fast PROCHOT: Respond to PROCHOT# within 1uS of PROCHOT# pin assertion, reducing the processor power.
  • PROCHOT Demotion Algorithm: designed to improve system performance during multiple PROCHOT assertions.
