BDM and JTAG Timing
Table 16 provides the BDM timing parameters.
Figure 5 provides the JTAG timing diagram and Table 17 provides the JTAG timing parameters.
Figure 5. JTAG Timing Diagram
1 Note that output data may go invalid before rising edge of the clock. To clock data in reliably, you need to sample data, for
example, 2 ns before rising edge of clock.
2 Timing figure given takes 50% margin for noise and uncertainty on pin capacitance. Simulated clock-to-data, not taking noise
effects into account is 2.7 ns.
