AC SWITCHING CHARACTERISTICS AND WAVEFORMS
The AC specifications provided in the AC characteris-
tics tables that follow consist of output delays, input
setup requirements, and input hold requirements. Fig-
ure 31 provides a key to the switching waveforms.
AC specifications measurement is defined by the fig-
ures that follow each timing table.
Output delays are specified with minimum and maxi-
mum limits, measured as shown. The minimum delay
times are hold times provided to external circuitry.
Input setup and hold times are specified as minimums,
defining the smallest acceptable sampling window.
Within the sampling window, a synchronous input sig-
nal must be stable for correct microcontroller operation.

Notes:
For AC testing, inputs are driven at 3 V for a logic 1 and 0 V for a logic 0.
