Table 9. Signal Functional Description (Sheet 8 of 8)
Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3kΩ to OV
3. Must pull down (recommended value is 1kΩ)
4. If not used, must pull up (recommended value is 3kΩ to OV
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 for logic and I/O voltage.
Ground for system PLL voltage (analog).
Ground for Ethernet PLL voltage (analog).
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—Logic voltage.
+3.3V—I/O (except DDR2 SDRAM and Ethernet).
+2.5V—I/O Ethernet.
+1.8V (DDR2) or +2.5V (DDR1)—I/O DDR SDRAM.
+1.5V—Filtered voltage for system PLLs (analog).
+1.5V—Filtered voltage for Ethernet PLLs (analog).
To avoid noise pickup, the balls on this chip classified as
Reserved must be connected as shown in Table 8 on
page 55.
