Power-on Reset
ATtiny25/45/85
Figure 8-1.
A Power-on Reset (POR) pulse is generated by an On-chip detection circuit. The detection level
is defined in
POR circuit can be used to trigger the Start-up Reset, as well as to detect a failure in supply
voltage.
A Power-on Reset (POR) circuit ensures that the device is reset from Power-on. Reaching the
Power-on Reset threshold voltage invokes the delay counter, which determines how long the
device is kept in RESET after V
