4.2.2

NVUSRO[OSCILLATOR_MARGIN] field description

The fast external crystal oscillator consumption is dependent on the OSCILLATOR_MARGIN bit value. Table 9 shows how

NVUSRO[OSCILLATOR_MARGIN] controls the device configuration.

4.2.3

NVUSRO[WATCHDOG_EN] field description

The watchdog enable/disable configuration after reset is dependent on the WATCHDOG_EN bit value. Table 10 shows how

NVUSRO[WATCHDOG_EN] controls the device configuration.
