Table 2-12
, the Terminal Functions table, identifies the external signal names, the associated pin/ball
numbers along with the mechanical package designator, the pin type (I, O, IO, OZ, or PWR), whether the
pin/ball has any internal pullup/pulldown resistors, whether the pin/ball is configurable as an IO in GPIO
mode, and a functional pin description.

TYPE column refers to pin direction in functional mode. If a pin has more than one function with different directions, the functions are
separated with a slash (/).
PULL column:
IPD = Internal Pulldown resistor
IPU = Internal Pullup resistor
If the GPIO column is 'Y', then in GPIO mode, the pin is configurable as an IO unless otherwise marked.
