Abstract

A method for changing an operating mode of at least one device, multiple compare registers, each having a bit pattern, being associated with the at least one device, is provided in which a data packet transmitted via a network is received by the at least one device, a content of the data packet being compared to the bit patterns of the associated compare registers, and in which a change in the operating mode of the at least one device takes place when the at least one device detects conformity of a bit pattern of the associated compare registers with the content of the data packet.

Claims

1-10. -10. (canceled)

11. A method for changing an operating mode of at least one device, multiple compare registers each having a bit pattern associated with the at least one device, the method comprising:

receiving, by the at least one device, a data packet transmitted via a network, a content of the data packet being compared to the bit patterns of the associated compare registers; and

changing the operating mode of the at least one device when the at least one device detects conformity of the bit patterns of the associated compare registers with the content of the data packet.

12. The method according to claim 11, wherein, in an event of a change in the operating mode, the at least one device is changed at least one of from a hibernation or sleep mode to a wake-up mode, and from a wake-up mode to a hibernation or sleep mode.

13. The method according to claim 11, further comprising:

defining multiple devices within the network as a group of devices, at least one compare register having a bit pattern identical to that of the devices being associated with all devices of the group; and

changing operating modes of the devices of the group when the devices detect conformity of the identical bit pattern with the content of the received data packet.

14. The method according to claim 11, further comprising:

activating or deactivating a compare register via the bit pattern stored in the compare register.

15. The method according to claim 11, further comprising:

chaining multiple compare registers to one compare register.

16. The method according to claim 11, further comprising:

storing a standard bit pattern in the compare registers after the at least one device is switched on or reset.

17. The method according to claim 11, wherein the at least one device is configured as a node of a cable-bound network for transmission of data.

18. The method according to claim 11, wherein the at least one device is configured as a node of a network situated in a motor vehicle.

19. A device with which multiple compare registers, each having a bit pattern, are associated, the device configured to receive a data packet which is transmitted via a network, to compare a content of the data packet to the bit patterns of the associated compare registers, and to perform a change in an operating mode when the device detects conformity of the bit patterns of the associated compare registers with the content of the data packet.

20. The device according to claim 19, wherein the compare registers are configured as configurable memory cells.
