Abstract

Configuration devices in a module. In some embodiments a radio-frequency module includes a serial bus including a first serial data line and a second serial data line. The radio-frequency module also includes a control component coupled to the serial bus and the first switch, the control component configured to determine whether first data is detected on the first serial data line, determine whether second data is detected on the second serial data line, and decode a command based on the first data and second data when the first data is detected on the first serial data line and when the second data is detected on the second serial data line.

First claim

What is claimed is:

1. A radio-frequency module comprising:
a serial bus including a clock line associated with a -clock signal, a first serial data line associated with serial data, and a second serial data line associated with serial data; and
a control component coupled to the serial bus and a first switch, the control component configured to determine whether first data is detected on the first serial data line, determine whether second data is detected on the second serial data line, and decode a command based on the first data and the second data when the first data is detected on the first serial data line and when the second data is detected on the second serial data line, the first data and the second data each including a portion of the command, the control component further configured to decode the command based on the first data when the first data is detected on the first serial data line and when the second data is not detected on the second serial data line.

2. The radio-frequency module of claim 1 wherein the control component is further configured to configure a first device based on the command.

3. The radio-frequency module of claim 2 wherein the control component is configured to configure the first device by accessing a register based on the command, the register including state information for the first device.

4. The radio-frequency module of claim 2 further comprising the first device.

5. The radio-frequency module of claim 2 wherein the radio-frequency module is coupled to the first device via a third data line.

6. The radio-frequency module of claim 1 wherein the command is in a first format when the first data is detected on the first serial data line and when the second data is detected on the second serial data line.

7. The radio-frequency module of claim 6 wherein the command is in a second format when the first data is detected on the first serial data line and when the second data is not detected on the second serial data line.

8. The radio-frequency module of claim 7 wherein the second format includes a radio-frequency front-end (RFFE) format.

9. The radio-frequency module of claim 1 wherein the radio-frequency module includes a front-end module (FEM).

10. The radio-frequency module of claim 1 wherein the radio-frequency module includes a master device.

11. The radio-frequency module of claim 2 wherein the first device includes a slave device.

12. A method comprising:
determining, by a control component, whether first data is detected on a first serial data line of a serial bus of a radio-frequency module, the first serial data line associated with serial data, the serial bus including a clock line associated with a clock signal;
determining, by the control component, whether second data is detected on a second serial data line of the serial bus of the radio-frequency module, the second data line associated with serial data;
decoding, by the control component, a command received on the serial bus based on the first data and the second data in response to detecting the first data on the first serial data line and detecting the second data on the second serial data line, the first data and the second data each including a portion of the command; and
decoding, by the control component, the command based on the first data in response to detecting the first data on the first serial data line and not detecting the second data on the second serial data line.

13. The method of claim 12 further comprising configuring a first device based on the command.

14. The method of claim 13 wherein the configuring the first device includes accessing a register based on the command, the register including state information for the first device.

15. The method of claim 14 wherein the radio-frequency module is coupled to the first device via a third data line.

16. The method of claim 12 wherein the command is in a first format when the first data is detected on the first serial data line and when the second data is detected on the second serial data line.

17. The method of claim 16 wherein the command is in a second format when the first data is detected on the first serial data line and when the second data is not detected on the second serial data line.

18. A wireless device comprising:
a serial bus including a clock line associated with a -clock signal, a first serial data line associated with serial data, and a second serial data line associated with serial data; and
a control component coupled to the serial bus and a first switch, the control component configured to determine whether first data is detected on the first serial data line, determine whether second data is detected on the second serial data line, and decode a command based on the first data and the second data when the first data is detected on the first serial data line and when the second data is detected on the second serial data line, the first data and the second data each including a portion of the command, the control component further configured to decode the command based on the first data when the first data is detected on the first serial data line and when the second data is not detected on the second serial data line.

19. The wireless device of claim 18 wherein the control component is further configured to configure a first device based on the command.

20. The wireless device of claim 19 wherein the control component is configured to configure the first device by accessing a register based on the command, the register including state information for the first device.
