8.7 AC Characteristics

The following tables list the AC characteristics including output delays, input setup requirements, input hold requirements

Input or output signals must cross these levels during testing.

Input setup and hold times are specified minimums that define the smallest acceptable sampling window for which a syn-

chronous input signal must be stable for correct operation.

The interface signal groups listed in Table 11. adhere to the timing parameters given in the corresponding specification.

For details, refer to those specifications.
