Power-on Reset
Figure 6-1.
A Power-on Reset (POR) pulse is generated by an On-chip detection circuit. The detection
level is defined in
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.
