AC TEST REFERENCE WAVEFORMS

5.0 V PCMCIA AC Test Reference Waveform

This waveform indicates the AC testing method em-
ployed for all signals that are PCMCIA bus signals when

the PCMCIA power supply pins are set to 5.0 V (i.e.,
VDDP pins = 5.0 V).

3.3 V PCMCIA AC Test Reference Waveform

This waveform indicates the AC testing method em-
ployed for all signals that are PCMCIA bus signals when

the PCMCIA power supply pins are set to 3.3 V (i.e.,
VDDP pins = 3.3 V).
