N32G43x&N32L43x&N32L40x Series MSI Frequency Trimming Application Notes
■This document describes the MSI frequency trimming method, Convenient for users to adjust the frequency of MSI according to their actual needs during normal use.
■This document is applicable to N32G43x&N32L43x&N32L40x series products of National Technology.
●Overview
■After the multi-speed internal(MSI) RC oscillator of N32G43x&N32L43x&N32L40x is packaged by the packaging factor or there may be a frequency offset problem after users produce reflow. For example, the maxium deviation that may occur after reflow is about 2% of the nominal value.Because MSI frequency offset issues may cause problems with the operation of peripherals using MSI as a clock source,it is necessary to correct the frequency of MSI.
