Power-on Reset
Figure 9-1.
A Power-on Reset (POR) pulse is generated by an On-chip detection circuit. The detection level
is defined in
ever V
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
when V
