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).
+3.3V—Filtered voltage for USB PLL (analog).
Connect to OV
+3.3V—Filtered voltage for USB PHY (analog).
Connect to OV
