15.4.8 Reference Clock Output (REFOx)

The PIC32AK1216GC41064 family features one or more reference clock output (REFOx) modules. The REFOx module clock source is one of the CLKGENs (see Table 15-2 for assignments of CLKGENs to REFOx). The input clock to the REFOx is therefore the clock source of the associated CLKGENx, which can be any of the sources defined in Table 15-3. This selection includes reference clock inputs (REFIx) that are mappable to device pins using peripheral pin select (PPS). The REFO output signal is internally routed to select peripherals and can be routed to a device pin using PPS. Figure 15-15 illustrates REFO interconnections.
