B. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control.

Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control.

D. The outputs are measured one at a time, with one transition per measurement.

J. All parameters and waveforms are not applicable to all devices.
