1 The output valid (max) value in this column applies for the standard 30 pF capacitive load used in testing. To see how output valid varies with capacitive loading, see Figure 40
2 The external port protocols employ bus IDLE cycles for bus mastership transitions as well as slave address boundary crossings to avoid any potential bus contention. The
apparent driver overlap, due to output disables being larger than output enables, is not actual.
3 CPA and DPA pins are open drains and have 0.5 k internal pull-ups.
4 These input pins have Schmitt triggers and therefore do not need to be synchronized to a clock reference. These synchronous specifications only apply for recognition in the
current clock reference cycle.
5 This pin is a strap option. During reset, an internal resistor pulls the pin low.
6 For input specifications, see Table 21.
7 For additional requirement details, see Reset and Booting on Page 9.
8 TCK_FE indicates TCK falling edge.
9 These pins may change only during reset; recommend connecting it to VDD_IO/VSS.
10Reference clock depends on function.
