SERIAL COMMUNICATION METHOD
First Claim
1. A serial communication method for a layered communication architecture including 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 comprising:
- transferring a first signal to the second layer based on a signal received through a communication line, said transferring the first signal performed by the first layer;
informing the third layer of reception of the first signal, said informing performed by the second layer;
responding to the second layer based on whether there is a task to be performed, said responding performed by the third layer;
transferring a second signal to the first layer based on a response from the third layer, said transferring the second signal performed by the second layer; and
entering a first power saving state according to the second signal, said entering the first power saving state performed by the first layer.

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.

8. A serial communication method used in a universal flash storage (UFS) interface between a host and a device, the serial communication method comprising:
-
receiving at a mobile industry processor interface (MIPI) M-PHY layer of the device a signal corresponding to a first symbol through a communication line and transferring the first symbol to an MIPI UniPro layer of the device; informing an application layer of the device of reception of the first symbol, said informing performed by the MIPI UniPro layer; responding to the MIPI UniPro layer based on whether there is a task to be performed, said responding performed by the application layer; requesting the MIPI M-PHY layer to enter a first power saving state based on a response from the application layer, said requesting performed by the MIPI UniPro layer; and entering the first power saving state in response to the request for entry to the first power saving state, said entering performed by the MIPI M-PHY layer. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A serial communication method between first and second devices, comprising:
-
entering a communication mode to serially transmit and receive data between the first and second devices; receiving a first symbol at the second device from the first device; determining if data is available for transmission at the second device, responsive to receipt of the first symbol; transmitting the first symbol from the second device to the first device upon determination that data is not available for transmission at the second device; entering a power saving state at the second device responsive to the received first symbol, after said transmitting the first symbol to the first device; determining at the second device whether a communication line between the first and second devices transitions from a first logic level to a second logic level; and escaping from the power saving state at the second device upon determination of the transition. - View Dependent Claims (17, 18, 19, 20)
