Power-On Reset (POR) and Initialization The Power-On-Reset circuit (POR) maintains the circuit in a reset state until an adequate inter- nal operating voltage threshold level has been reached, whereupon a default start-up delay sequence is started. During this period ...

... Tag IDs. This is an important issue as the Tag ID is used as the basis for accessing and sorting tags during anticollision commands GetID, Select and SelectGroup. The Atmel traceability code (blocks 60 and 59) itself provides a means of unique chip identifica- tion so that this data content can be used as the Tag part of the Tag ID by copying it or part of it into blocks 56 and 57 ...
