The control signal includes a chip select (CS) signal and/or a wait-for-interrupt (WFI) signal, and the power mode includes a light sleep (LS) mode and/or a deep sleep (DS) mode. The frequency information represents a low frequency range, medium frequency range, and/or high frequency range. A corresponding computer-readable medium, power management controller, and electronic system are also disclosed.
