12.3.2.1.1 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 reach the POR treshold voltage. The POR is always enabled and will also detect when the V_DD falls below the treshold voltage.

All logic is reset on POR and registers that are loaded with fuse values will be reloaded during the reset sequence.
