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).
This includes ISA signals, TAI interface signals, Mem-
ory Bus Interface signals, IEEE 1149.1 signals and any
other signal not considered to be part of the PCMCIA
bus interface.

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
Interface signals, IEEE 1149.1 signals and any
other signal not considered to be part of the PCMCIA
bus interface.
