This application note gives an overview of the Clock Supervisor. Purpose of the Clock Supervisor is the supervision of the Main and Sub oscillators. In case of oscillation (OSCMAIN or OSCSUB) failure the Clock Supervisor control logic will take action, i.e. switching to an internal RC-oscillation clock (CLKRC 100 kHz), depending on the operation mode set in the control register.
