Test 1: The following inputs should remain steady at VCC or GND state to minimize sleep current: A0-A2, D0-D7, IOR#,
IOW#, CS# and modem inputs. Also, RX input must idle at logic 1 state while in sleep mode. In mixed voltage environ-
ments, where the voltage at any of the inputs of the 651 is lower than its VCC supply voltage, the sleep current will be high-
er than the maximum values given here.
