Pin States Through Reset
This chapter describes the states of each signal before, during and directly after reset. 
Additionally, Some signals have internal pull-up/pull-down termination resistors, and 
their values are also provided (Term). Termination tolerances are +/- 50% unless 
otherwise specified by electrical specs (PCIe*, and other differential termination). All 
signals with the “†” symbol are muxed and may not be available without configuration. 
See 
.
Note:
The internal termination resistor values & pull directions described in this 
chapter are the power-on defaults. Firmware & software may change the 
termination value, pull direction or disable the termination completely, on a 
pin-by-pin basis, using the _PCONF0 register corresponding to that pin.
