External Reset
An External Reset is generated by a low level on the RESET pin if enabled. Reset pulses longer
than the minimum pulse width (see “System and Reset Characteristics” on page 176) will gener-
ate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a
reset. When the applied signal reaches the Reset Threshold Voltage – V
RST – on its positive
edge, the delay counter starts the MCU after the Time-out period – t
TOUT – has expired.

Brown-out Detection
ATtiny24A/44A/84A 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
8-5 on page 40), the Brown-out Reset is immediately activated. When V
CC increases above the
trigger level (V
BOT+ in Figure 8-5 on page 40), 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
