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
environments, where the voltage at any of the inputs of the 651 is lower than its VCC supply voltage, the sleep current will
be higher than the maximum values given here.
