9.4.5 Oscillator

To support independent operation with its controller, the module includes a built-in oscillator. A built-in 70 kHz oscillator maintains input source monitoring if the system oscillator fails due to dependency on monitored input sources. It is designed to operate without having to depend on any V_DDCORE level logic and/or the associated voltage source (i.e., LDO), most likely the sources being monitored.
