Notes:
1. Receiver input has hysteresis
2. Must pull up (recommended value is 3 kΩ to OV
3. Must pull down (recommended value is 1 kΩ)
4. If not used, must pull up (recommended value is 3 kΩ to OV
5. If not used, must pull down (recommended value is 1 kΩ)
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.
+1.5 V—Logic voltage.
+3.3 V— I/O (except DDR2 SDRAM and Ethernet).
+2.5 V— I/O Ethernet.
+1.8 V (DDR2) or +2.5 V (DDR1)— I/O DDR SDRAM.
Ground for logic and I/O voltage.
