1. A sleep-mode detection method, comprising:
transmitting a Devslp command to at least one signal pin of a second transmitting port of a device under test by a first transmitting port, wherein the first transmitting port is compatible with a first interface standard, and the second transmitting port is compatible with a second interface; pulling high voltage level at a control pin of the second transmitting port by a third transmitting port compatible with a third interface when the first transmitting port receives a first response corresponding to the Devslp command from the device under test to enable the device under test to enter a sleep mode, wherein the third interface is different from the first interface and the second interface, and the third transmitting port is arranged to be coupled to the control pin of the second transmitting port; pulling low the voltage level at the control pin and transmitting a Comwake signal to the signal pin by the third transmitting port after the voltage level at the control pin is pulling high a first predetermined period to enable the device under test to enter a normal operating mode from the sleep mode; determining whether the first transmitting port receives a second response corresponding to the Comwake signal from the device under test in a second predetermined period; and determining that the sleep mode of the device under test meets a specification and outputting a result indicating the sleep mode that meets the specification when the first transmitting port receives the second |
