4.2 Terminal Functions
Table 4-1 through Table 4-16 identify the external signal names, the associated pin numbers along with
the mechanical package designator, the pin type (Input, Output, I/O, Power, or Ground), whether the pin
has any internal pullup/pulldown, whether the pin can be configured as a GPIO, and a functional pin
description.
NOTE
In the Terminal Functions table below, the "Reset Pull State" is the state of the pull applied to
the terminal while nPORRST is low and immediately after nPORRST goes High. The default
pull direction may change when software configures the pin for an alternate function. The
"Pull Type" is the type of pull asserted when the signal name in bold is enabled for the given
terminal by the IOMM control registers.
All I/O signals except nRST are configured as inputs while nPORRST is low and
immediately after nPORRST goes High. While nPORRST is low, the input buffers
are disabled, and the output buffers are disabled with the default pulls enabled.
All output-only signals have the output buffer disabled and the default pull enabled
while nPORRST is low, and are configured as outputs with the pulls disabled
immediately after nPORRST goes High.
