Signal Functional Description
Multiplexed signals are shown in brackets following the first signal name assigned to each multiplexed ball.
Notes:
1. Receiver input has hysteresis.
2. Must pull up. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
3. Must pull down. See “Pull-Up and Pull-Down Resistors” on page 29 for recommended termination values.
4. If not used, must pull up.
5. If not used, must pull down.
6. Strapping input during reset; pull up or pull down as required.
7. Pull-up may be required. See “External Bus Control Signals” on page 29.

DD
Trace interface clock. A toggling signal that is always half of the CPU
core frequency. To access this function, software must toggle a DCR
bit
or
General Purpose I/O.
Note: Initialization strapping must hold this pin low (0) during reset.
Ground
Output driver voltage—3.3V.
Logic voltage—1.8V.
Reserved—Except for AF4, do not connect signals, voltage, or
ground to these pins. AF4 must be tied to OV
