49 / 380 page  49 8059D–AVR–11/09 ATmega1284P Figure 9-1. Reset Logic 9.1.2 Power-on Reset A Power-on Reset (POR) pulse is generated by an On-chip detection circuit. The detection level is defined in ”System and Reset Characteristics” on page 327. The POR is activated whenever V CC is below the detection level. The 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 CC rise. The RESET signal is activated again, without any delay, when V CC decreases below the detection level.
