Catastrophic Thermal Trip: 

When low, this signal 

indicates that a thermal trip 

from the processor occurred 

and has reached an operating 

temperature that may 

damage the part.

Processor Hot: PROCHOT_B 

goes active when the SoC 

temperature monitoring 

sensor(s) detects that the SoC 

has reached its maximum safe 

operating temperature. This 

indicates that the SoC 

Thermal Control Circuit (TCC) 

has been activated, if 

enabled. This signal can also 

be driven to the processor to 

activate the TCC. The platform 

board must ignore this SoC 

output signal while 

PMU_PLTRST_B (active-low 

SoC output) is asserted.

Memory Hot: Input from the 

platform to indicate a memory 

overheating scenario. The 

active low signal causes the 

SoC to perform memory 

throttling in an attempt to 

cool the memory. The 

platform board must ignore 

this SoC output signal while 

PMU_PLTRST_B (active-low 

SoC output) is asserted.
