TDO

TDO (Test Data Out) transfers serial test data out of 
the processor. TDO provides the serial output needed for 
JTAG specification support.

O

TAP

OD

TMS

TMS (Test Mode Select) is a JTAG specification support 
signal used by debug tools.

I

TAP

OD

TRST#

TRST# (Test Reset) resets the Test Access Port (TAP) 
logic. TRST# must be driven low during power on Reset.

PROCHOT#

Processor Hot#: This will go active when the 
processor temperature monitoring sensor(s) detects 
that the processor has reached its maximum safe 
operation temperature
Output: This indicates that the processor Thermal 
Control Circuit (TCC) has been activated, if enabled.
Input: This signal can also be driven to the processor to 
activate the TCC.

I/O

I: CMOS
O: OD

THERMTRIP# Thermal Trip: The processor protects itself from 

catastrophic overheating by use of an internal thermal 
sensor. This sensor is set well above the normal 
operating temperature to ensure that there are no false 
trips. The processor will stop all execution when the 
junction temperature exceeds approximately 125°C. 
This is signaled to the system by the THERMTRIP# pin.

O

Open 
Drain

VCC

Processor-core power supply. The voltage supplied to 
these pins is determined by the VID pins.

PWR

VCC_SENSE

VCC_SENSE and VSS_SENSE provide an isolated, low 
impedance connection to the processor core voltage 
and ground. They can be used to sense or measure 
voltage near the silicon.
