4.1 CLKREF - Clock Reference

4.1.1 Introduction

The MPLAB® Code Configurator (MCC) Melody Clock Reference Peripheral Library (PLIBs) drivers generates APIs to support CLKREF-specific peripheral functionality on target MCUs.

The Clock Reference (CLKREF) output module provides the ability to send a clock signal to the clock reference output pin (CLKR). The reference clock output can be routed internally as an input signal for other peripherals, such as the timers and CLCs.

The reference clock output module has the following features:
  • Selectable clock source using the CLKRCLK register
  • Programmable clock divider
  • Selectable duty cycle
