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; the 
values are also provided. All signals with the “†” symbol are multiplexed and may not 
be available without configuration. See 
.

Default Buffer State Definitions (Sheet 1 of 2)
Buffer State
Description
High-Z
The processor places this output in a high-impedance state. For inputs, external drivers are 
not expected.
Do Not Care
The state of the input (driven or tri-stated) does not affect the processor. For outputs, it is 
assumed that the output buffer is in a high-impedance state.
V
OH
The processor drives this signal high with a termination of 50 Ω.
V
OL
The processor drives this signal low with a termination of 50 Ω.
Unknown
The Processor drives or expects an indeterminate value.
V
IH
The processor expects/requires the signal to be driven high.
V
IL
The processor expects/requires the signal to be driven low.
