Table 9. Signal Functional Description (Sheet 8 of 8)
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.
Additional information on trace execution and branch status.
Ground.
PLL (analog) voltage ground.
PLL (analog) memory voltage ground.
Trace data capture clock, runs at 1/4 the frequency of the
processor.
Trace Execution Status is presented every fourth processor
clock cycle.
1.5V supply—Logic voltage.
3.3V supply—I/O (except DDR SDRAM, Ethernet).
2.5V supply—SDRAM, Ethernet.
1.5V—Filtered voltage for system PLLs (analog).
1.5V—Filtered voltage for memory PLL (analog).
To avoid noise pickup problems, most of these balls must be
connected in the board design as shown Table 8 on page 51.
