Abstract
A packaged circuit includes an internal circuit, an embedded clock generator, a plurality of multi-function pins and a control pad. The embedded clock generator is for generating an internal clock. The pins include a clock output pin and a clock input pin. The clock output pin outputs the internal clock generated by the embedded clock generator. The clock input pin is for receiving an external clock. The control pad receives a control signal to determine whether the internal circuit utilizes a system clock according to the internal clock generated by the embedded clock generator or the external clock received by the clock input pin.
