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
whenever V
Reset, as well as to detect a failure in supply voltage.
A 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
decreases below the detection level.
