pin function
8.This paper introduces the structure and pin function of plug-in circuits based on UDA1341 digital audio interface,presents the realizing method for this interface to connect S3C2410 hardware with UDA1341 in an embedded system,while introduces the IIS bus format and application design based on embedded system.
9.Further, the comparisons and analyses are made for both the current modes of APFC and the corresponding control methods, and thus the continuous current mode and the average current mode control are adopted in this design. In addition, UC3854 is used as the control integrated circuit (IC) in APFC, and its working principle and pin function are introduced.
