13.8.6.1.2.1 PD0

PD0 is the lowest Power Domain. It contains the Event System, the Generic Clock Controller, Oscillators Controller, the Main Clocks Controller. Additionally, PD0 contains a number of peripherals that allow the device to wake up from an interrupt: one SERCOM (SERCOM5), one Timer/Counter (TC4), ADC, AC, CCL and the PTC. The PLL oscillator sources, DFLL48M and FDPLL96M, are in PD0 as well.

This power domain will automatically be activated if either PD1 or PD2 are activated.
