PD1

PD1 is the intermediate Power Domain. PD1 contains the DMA controller, the Peripheral Access Controller, and the Low Power Bus Matrix. It also contains the Timer/Counter for Control instances, the AES peripheral, the TRNG, the DAC and the low-power SRAM. PD1 contains the SERCOMs (except for SERCOM5, present in PD0), and the Timer Counters (except TC4, present in PD0).

When active, PD1 automatically activates PD0.
