Abstract
Systems and methods are disclosed for an audio processor that includes a clock detection circuit and a clock bypass circuit. According to various embodiments, the clock detection circuit can check and indicate the status of a main clock and upon detection of a loss of the main clock, the clock bypass circuit can switch the source of the main clock to an alternate source such as an on chip oscillator allowing the system to gracefully recover from the clock loss event.
