This application note describes the operation of the dual clock comparator (DCC) computation tool, made to be used with the Sitara™ AM263x MCU. This tool provides the pre-computed register values to be programmed, in order to check if any required system/peripheral clock frequency is within a specific accuracy % by comparing it against a reference clock, enabling easy integration into your application code.
