An External Reset is generated by a low level on the RESET pin. Reset pulses longer than the
minimum pulse width (see

Figure 6-4.
ATtiny87/167 has an On-chip Brown-out Detection (BOD) circuit for monitoring the Vcc level
during operation by comparing it to a fixed trigger level. The trigger level for the BOD can be
selected by the BODLEVEL Fuses

tion level should be interpreted as V

The BOD circuit will only detect a drop in Vcc if the voltage stays below the trigger level for lon-
