2.4 Terminal Functions
Section 2.4.1 and Section 2.4.2 identify the external signal names, the associated pin/ball numbers along
with the mechanical package designator, the pin/ball type (Input, Output, IO, Power or Ground), whether
the pin/ball has any internal pullup/pulldown, whether the pin/ball can be configured as a GIO, and a
functional pin/ball description. The first signal name listed is the primary function for that terminal. The
signal name in Bold is the function being described. Refer to the I/O Multiplexing Module (IOMM) User
Guide for information on how to select between different multiplexed functions.
NOTE
All I/O signals except nRST are configured as inputs while nPORRST is low and immediately
after nPORRST goes High.
All output-only signals are configured as inputs while nPORRST is low, and are configured
as outputs immediately after nPORRST goes High.
While nPORRST is low, the input buffers are disabled, and the output buffers are tri-stated.
