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.
2
For input specifications on FLAG3–0 pins, see
Table 17
.
3
These input pins are asynchronous and therefore do not need to be synchronized to a clock reference.
4
For additional requirement details, see
Reset and Booting on page 9
.
5
Reference clock depends on function.
6
These pins may change only during reset; recommend connecting it to V
