Abstract: A serial communication method for a layered communication architecture includes a first layer, a second layer that is higher than the first layer, and a third layer that is higher than the second layer. The serial communication method includes transferring a first signal to the second layer based on a signal received through a communication line, the transferring performed by the first layer. The serial communication method further includes informing the third layer of reception of the first signal, the informing performed by the second layer; responding to the second layer based on whether there is a task to be performed, the responding performed by the third layer; transferring a second signal to the first layer based on a response from the third layer the transferring performed by the second layer; and entering a power saving state according to the second signal, the entering performed by the first layer.
