33.4.1 Watchdog Clock Inputs

The Sleep Mode Counter always uses the 32 kHz clock source, which is typically connected to a BFRC/244 oscillator. The Run Mode Counter will use the clock source selected by the RMCLK[1:0] in (WDTCON[7:6]).

Note: The BFRC/244 oscillator is automatically enabled whenever it is being used as a WDT clock source and the WDT is enabled.
