External Reset
Atmel ATtiny24/44/84 [Preliminary]
Figure 9-3.
Table 9-1.
Note:
An External Reset is generated by a low level on the RESET pin if enabled. Reset pulses lon-
ger than the minimum pulse width (see
will generate 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
its positive edge, the delay counter starts the MCU after the Time-out period – t
expired.
