Reset Logic

9.2.1

Power-on Reset

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

is defined in ”System and Reset Characterizations” on page 309. The POR is activated when-

ever V

CC 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 V

CC rise. The RESET signal is activated again, without any delay,

when V

CC decreases below the detection level.
