Terminal Functions

The terminal functions table (Table 1−6) identifies the external signal names, the associated pin (ball) numbers

along with the mechanical package designator, the pin type (I, O/Z, or I/O/Z), whether the pin has any internal

pullup/pulldown resistors and a functional pin description. For more detailed information on device

configuration, peripheral selection, multiplexed/shared pins, and debugging considerations, see the Device

Configurations section of this data sheet.
