13.3.2.1.1 Power-On Reset (POR)

A Power-on-Reset (POR) is generated by an on-chip detection circuit. The POR is activated when the V_DD rises until it reaches the POR threshold voltage. The POR is always enabled and will also detect when the V_DD falls below the threshold voltage.

All volatile logic is reset on POR. All fuses are reloaded after the Reset is released.
