5.0 V Non-Pcmcia Ac Test Reference Waveform - AMD Am79C930 Preliminary Manual

5.0 V NON-PCMCIA AC TEST REFERENCE WAVEFORM

This waveform indicates the AC testing method em-
ployed for all signals that are not PCMCIA bus signals
when the appropriate power supply pins are set to
5.0 V (i.e., VDDT, VDDU1, VDDU2, VDDM pins = 5.0 V).
output
3.3 V NON-PCMCIA AC TEST REFERENCE WAVEFORM
This waveform indicates the AC testing method em-
ployed for all signals that are not PCMCIA bus signals
when the appropriate power supply pins are set to 3.3 V
(i.e., VDDT, VDDU1, VDDU2, VDDM pins = 3.3 V). This
includes ISA signals, TAI interface signals, Memory Bus
