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
V
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
CC
BODLEVEL [2..0]
is below the detection level. The POR circuit can be used to trigger the start-up Reset, as
CC
decreases below the detection level.
