Datasheet

Note:
1. Actual Start-Up time is 1 OSCULP32K cycle + 3 XOSC32K cycles.
2. The given time assumes an XTAL frequency of 32.768kHz.
Bit 7 – ONDEMAND On Demand Control
This bit controls how the XOSC32K behaves when a peripheral clock request is detected. For details,
refer to Table 29-1.
Bit 6 – RUNSTDBY Run in Standby
