Test 1: The following inputs must remain steady at VCC or GND state to minimize Sleep current: A0-A2, D0-
D7, IOR#, IOW#, CS#, CHSEL, and all modem inputs. Also, RXA and RXB inputs must idle at logic 1 state
while asleep. Floating inputs will result in sleep currents in the mA range. For PowerSave feature that isolates
address, data and control signals, please see the XR16L2551 datasheet.
