It is valid for the devices indicated in the revision history. The specifications are subject to change without notice. *WARNING: Stressing the device beyond the Absolute Maximum Ratings may cause permanent damage. These are stress ratings only. Operation beyond the Operating Conditions is not recommended and ex- tended exposure beyond the Operating Conditions may affect device reliability. itors is application and board layout dependent. The processor can cause transient power surges when its output buffers transition, particularly when con- nected to large capacitive loads. Always connect any unused input pins to an appro- priate signal level. in particular, unused interrupt pins (NMI, INT3:0) should be connected to Vgg to avoid unwanted interrupts. Leave any unused output pin or any N.C. pin unconnected. 21
