8 SUPPLY, RESET AND CLOCK MANAGEMENT
The ST72334J/N-Auto, ST72314J/N-Auto and
ST72124J-Auto microcontrollers include a range
of utility features for securing the application in crit-
ical situations (for example, in case of a power
brown-out), and reducing the number of external
components. An overview is shown in
