20.3.1
A power-on event will generate an internal POR pulse
when a V
at the POR circuit threshold voltage (V
nominally
characteristics must meet specified starting voltage
and rise rate requirements. The POR pulse will reset a
POR timer and place the device in the Reset state. The
POR also selects the device clock source identified by
the oscillator configuration fuses.

The POR circuit inserts a small delay, T
nominally 10 μs and ensures that the device bias
circuits are stable. Furthermore, a user selected
