General Description

The ILO Trim component allows your application to determine the accuracy of the ILO. It provides a scaling function to allow the application to compensate for this inaccuracy. For PSoC 3 and PSoC 5LP devices, it can also directly improve the accuracy of the ILO by using a user-defined higher frequency, higher accuracy reference clock to count the number of ILO clock cycles. The derived information is then used to trim the ILO trim registers to incrementally approach the desired ILO frequency. The component supports both UDB and Fixed-Function implementations.
