Debug AC Timing Specifications
20.5 Debug AC Timing Specifications
Table 20-9 lists specifications for the debug AC timing parameters shown in Figure 20-16.
Figure 20-15 shows real-time trace timing for the values in Table 20-9.
Figure 20-16 shows BDM serial port AC timing for the values in Table 20-9.
