2.7 Terminal Functions
The terminal functions table ( Table 2-15 ) identifies the external signal names, the associated pin (ball) numbers, the
pin type (I, O/Z, or I/O/Z), whether the pin has any internal pullup/pulldown resistors, and gives functional pin
descriptions. This table is arranged by function. The power terminal functions table (
Table 2-16 ) lists the various
power supply pins and ground pins and gives functional pin descriptions. Table 2-17 shows all pins arranged by
signal name. Table 2-18 shows all pins arranged by ball number.
There are 17 pins that have a secondary function as well as a primary function. The secondary function is indicated
with a dagger (†).
For more detailed information on device configuration, peripheral selection, multiplexed/shared pins, and
pullup/pulldown resistors, see chapter
3 ‘‘Device Configuration’’ on page 67 .

IPD or IPU
Internal 100-μA pulldown or pullup is provided for this terminal. In most systems, a 1-k
Ω
resistor can
be used to oppose the IPD/IPU. For more detailed information on pulldown/pullup resistors and
situations in which external pulldown/pullup resistors are required, see the
Hardware Design Guide for
KeyStone Devices in 2.9 ‘‘Related Documentation from Texas Instruments’’ on page 66.
