External reset
Watchdog reset
The BODACT fuse determines the BOD setting for active mode and idle mode, while the
BODPD fuse determines the brown-out detection setting for all sleep modes except idle mode.
Table 9-3.
The External reset circuit is connected to the external RESET pin. The external reset will trigger
when the RESET pin is driven below the RESET pin threshold voltage, V
minimum pulse period t
includes an internal pull-up resistor.

The Watchdog Timer (WDT) is a system function for monitoring correct program operation. If the
WDT is not reset from the software within a programmable timout period, a Watchdog reset will
be given. The Watchdog reset is active for 1-2 clock cycles on the 2 MHz internal RC oscillator.
• Sampled: In this mode the BOD circuit will sample the VCC level with a period identical to
the 1 kHz output from the Ultra Low Power (ULP) oscillator. Between each sample the BOD is
turned off. This mode will reduce the power consumption compared to the enabled mode, but

If a brown-out is detected in this mode, the BOD circuit is set in enabled mode to ensure that
