1. A circuitry, comprising:
a multi-mode switching multiplexer, arranged to receive multiple mode settings, and select one of the multiple mode settings as an output mode setting;
a control circuit, arranged to generate a mode switching signal to control the multi-mode switching multiplexer; and
a receiver, arranged to receive an input signal and transmit a received signal to the control circuit, and further arranged to turn on or turn off at least one of its internal components according to the output mode setting;
wherein the multi-mode switching multiplexer receives the multiple mode settings from firmware, and the multiple mode settings are written into receiving terminals of the multi-mode switching multiplexer.
