Brown-out Detection
ATmega164P/324P/644P has an On-chip Brown-out Detection (BOD) circuit for monitoring the
V
CC level during operation by comparing it to a fixed trigger level. The trigger level for the BOD
can be selected by the BODLEVEL Fuses. The trigger level has a hysteresis to ensure spike
free Brown-out Detection. The hysteresis on the detection level should be interpreted as V
BOT+ =
V
BOT + VHYST/2 and VBOT- = VBOT - VHYST/2.
When the BOD is enabled, and V
CC decreases to a value below the trigger level (VBOT- in Figure
9-3 on page 52), the Brown-out Reset is immediately activated. When V
CC increases above the
trigger level (V
BOT+ in Figure 9-3 on page 52), the delay counter starts the MCU after the
Time-out period t
TOUT has expired.
The BOD circuit will only detect a drop in V
CC if the voltage stays below the trigger level for lon-
ger than t
Figure 9-3.

Watchdog Reset
When the Watchdog times out, it will generate a short reset pulse of one CK cycle duration. On
the falling edge of this pulse, the delay timer starts counting the Time-out period t
TOUT. Refer to
page 60 for details on operation of the Watchdog Timer.
