System and Reset Characteristics
ATtiny25/45/85
Standard Power-On Reset
Table 21-4.
Note:
Two versions of power-on reset have been implemented, as follows.
This implementation of power-on reset existed in early versions of ATtiny25/45/85. The table
below describes the characteristics of this power-on reset and it is valid for the following devices,
only:
Note:
Table 21-5.
