For an application in which the USB host function is to be used, use an oscillator having the accuracy and precision that satisfy the USB specifications. The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized in the following cases (see Figure 4): • Till the oscillation gets stabilized after VDD goes above the operating voltage lower limit. • Till the oscillation gets stabilized after the instruction for starting the main clock oscillation circuit is executed. • Till the oscillation gets stabilized after the HOLD mode is released. • Till the oscillation gets stabilized after the X'tal HOLD mode is released with CFSTOP (OCR register, bit 0) set to 0.
