# 2.2.4.1 MCC Clock Configuration

Clocks are configured to match the following distribution.

Figure 2-35.PIC32CXMTx Clock Distribution

This configuration optimizes the performance of the Demo Meter application and it must not be modified. It only requires the 32.768 kHz external oscillator to work. The following images summarize the MCC settings.

Important: The multichannel metrology library internally adjusts the PCK2 prescaler depending on its own configuration assuming that the PCK2 source has been previously configured as 8192000 Hz. In the case of the MCP391x, PCK2 output is internally configured as 8192000 Hz, using a PRES = 0.
