33.16 Debug AC Timing Specifications

Table 33-24 lists specifications for the debug AC timing parameters shown in Figure 33-21.

Table 33-24. Debug AC Timing Specification

Num Characteristic Min Max Units

D1 PST, DDATA to TCLK setup 5 ns

D2 TCLK to PST, DDATA hold 2 ns

DSI-to-DSCLK setup 1 CLKOUT

cycles

DSCLK and DSI are synchronized internally. D4 is measured from the

synchronized DSCLK input relative to the rising edge of CLKOUT.

DSCLK-to-DSO hold 4 CLKOUT

cycles

D5 DSCLK cycle time 5 CLKOUT
