摘要：An electronic apparatus for providing supply voltage to a first external device

with a predetermined pin assignment specification is provided. The electronic apparatusincludes a connection interface and a voltage supplier. The connection interface includesa first pin and a second pin. The voltage supplier provides a detection voltage signal tothe first pin and determines whether to provide the supply voltage according to whetherthe second pin is at a first level in response to the detection voltage signal. When thesecond pin is at the first level in response to the detection voltage signal, the voltagesupplier provides the supply voltage to the first pin.
