Data Sheet
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.
1.5V supply—Logic voltage.
3.3V supply—I/O (except DDR SDRAM, Ethernet).
2.5V supply—SDRAM, Ethernet.
Ground.
1.5V—Filtered voltage for system PLLs (analog).
PLL (analog) voltage ground.
1.5V—Filtered voltage for memory PLL (analog).
PLL (analog) memory voltage ground.
