 through 

 list the DC voltage, current, and power specifications for 

the processor. The voltage and current specifications are defined at the processor pins. 
Operational specifications listed in 

 through 

 are only valid while 

meeting specifications for case temperature, clock frequency, and input voltages.

This section describes the DC specifications of the system bus signals. The processor 
signal’s DC specifications are defined at the processor pins. 

 through 

describe the DC specifications for the AGTL+, PWRGOOD, HSTL clock, TAP port, system 
management, and LVTTL signals. Please refer to the ITP700 Debug Port Design Guide 
for the TAP connection signals’ DC specifications at the debug port.

3. The processor system bus is terminated at each end of the system bus. The processor supports both on-die

and off-die termination which is selected by the TERMA and TERMB pins. Termination tolerance is ±15% for

on-die termination measured at V
