PARAMETER CONTROL METHOD FOR INTEGRATED CIRCUIT AND INTEGRATED CIRCUIT USING THE SAME

摘要

A parameter control method for an integrated circuit and an integrated circuit using the same are provided. The method includes the steps of: providing a correspondence between 1^st to N^th impedance groups and 1^st to N^th first settings, wherein each impedance group includes K sub impedances; providing a correspondence between 1^st to K^th sub-impedance and 1^st to K^th second settings; detecting an impedance from a specific pin of the integrated circuit; comparing an impedance detected from the specific pin of the integrated circuit with the 1st to N^th impedance sets to find a corresponding specific impedance set to select a specific first setting; comparing the impedance detected from the specific pin of the integrated circuit with the 1^st to K^th sub-impedance of the specific impedance set to select a specific second setting; and operating the integrated circuit according to the specific first setting and the specific second setting.
