Signal Functional Description
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3kΩ to 3.3V)
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.

Note:
PLL (analog) voltage ground.
Ground.
1.5V—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, Ethernet)
2.5V supply—DDR SDRAM, Ethernet
1.5V supply—Logic voltage.
The trace signals, TrcTS0:6, are duplicated on two sets of
chip balls and are multiplexed with other signals in both
cases. This allows users to choose which set of
multiplexed signals they wish to use along with the
TrcTS0:6 signals. The trace signals in this set are primary
signals.
The trace signals in this set are secondary signals.
This trace signal is the primary signal.
