Power-on Reset
A power-on reset (POR) pulse is generated by an on-chip detection circuit. The detection level is defined in
Section 29.5 “System and Reset Characteristics” on page 272. The POR is activated whenever VCC 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 VCC rise. The RESET signal
is activated again, without any delay, when VCC decreases below the detection level.
