NOTE:
1. These parameters are verified in device characterization and are not 100% tested.
Figure 22: AC Input/Output Reference Waveform
NOTE:
1. AC test inputs are driven at VCCQ for a logic 1 and VSS for a logic 0. Input rise and fall times (10% to 90%) < 1.6ns.
2. Input timing begins at VCC/2. Due to the possibility of a difference between VCC and VCCQ, the input test point may not
be shown to scale.
3. Output timing ends at VCCQ/2.

NOTE:
All tests are performed with the outputs configured for
full drive strength (BCR[5] = 0).
