Abstract
The configuration of an apparatus for automatically calibrating a clock of a non-crystal oscillator and method thereof are disclosed. The proposed method for automatically calibrating the clock of the non-crystal oscillator includes sending a NACK signal to a host and fine-tuning the clock of the non-crystal oscillator via a frequency calibration system for non-crystal oscillator when a USB device receives an in-token command from the host, and outputting a datum from the USB device to the host.
