9 SUPPLY, RESET AND CLOCK MANAGEMENT
The ST72334J/N, ST72314J/N and ST72124J mi-
crocontrollers include a range of utility features for
securing the application in critical situations (for
example in case of a power brown-out), and re-
ducing the number of external components. An
overview is shown in
