Auto-powerdown can be disabled when FORCEON and FORCEOFF are high and should be done when driving
a serial mouse. With auto-powerdown enabled, the device is activated automatically when a valid signal is
applied to any receiver input. The INVALID output is used to notify the user if an RS-232 signal is present at any
receiver input. INVALID is high (valid data) if any receiver input voltage is greater than 2.7 V or less than – 2.7 V
or has been between – 0.3 V and 0.3 V for less than 30 µ s. INVALID is low (invalid data) if all receiver input
voltages are between – 0.3 V and 0.3 V for more than 30 µ s. Refer to Figure 5 for receiver input levels.
