It is necessary to ensure the PLL oscillation settling time when a power-on reset is initiated by low
level input on the PRESET pin during normal operation.
The timing of reset state indication on the STATUS[1:0] pins is asynchronous. The timing of
indicating normal operation is synchronous with the peripheral clock (Pck), and is therefore
asynchronous with the clocks input from the EXTAL pin and the CLKOUT pin.
