4.2 Signal Descriptions
The signal descriptions section shows pin information in module function order per package.
Section 4.2.1 and Section 4.2.2 identify the external signal names, the associated pin or ball numbers
along with the mechanical package designator, the pin or ball type (Input, Output, I/O, Power, or Ground),
whether the pin or ball has any internal pullup/pulldown, whether the pin or ball can be configured as a
GIO, and a functional pin or ball description. The first signal name listed is the primary function for that
terminal (pin or ball). The signal name in Bold is the function being described. For information on how to
select between different multiplexed functions, see Section 4.3, Pin Multiplexing, of this document or see
the I/O Multiplexing Module (IOMM) User Guide.
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 high impedance 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
high impedance.
In the Terminal Functions tables of Section 4.2.1 and Section 4.2.2, the RESET
PULL STATE is the state of the pullup or pulldown 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.
