Signal Functional Description
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3kΩ to 3.3V, 10kΩ to 5V)
3. Must pull down (recommended value is 1kΩ)
4. If not used, must pull up (recommended value is 3kΩ to 3.3V)
5. If not used, must pull down (recommended value is 1kΩ)
6. Strapping input during reset; pull-up or pull-down required

Signal Name
Trace branch execution status.
Trace data capture clock, runs at 1/4 the frequency of
the processor.
Trace Execution Status is presented every fourth
processor clock cycle.
Additional information on trace execution and branch
status.
PLL (analog) voltage ground.
Ground.
1.8V—Filtered voltages input for PLLs (analog circuits)
Note: A separate filter for each of the three voltages is
recommended.
3.3V supply—I/O (except DDR SDRAM)
2.5V supply—DDR SDRAM
1.8V supply—Logic voltage.
Do not connect signals, voltage, or ground to these
balls.
