Freescale Semiconductor MC9RS0

This device contains circuitry protecTIng against damage due to high staTIc voltage or electrical fields; however, it is advisedthat normal precauTIons be taken to avoid applicaTIon of any voltages higher than maximum-rated voltages to thishigh-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for

instance, VSS or VDD) or the programmable pull-up resistor associated with the pin is enabled.
