Abstract
A communication module includes: an amplification control device connected to a main device to receive, from the main device, a main signal including a command signal, an address signal that identifies an address of at least one register included in an antenna switch and a band select switch, and a write data signal to be recorded in a register corresponding to the address and interpret the command signal; and the antenna switch and the band select switch connected to the amplification control device via a first signal line where a clock signal is transmitted and a second signal line where a data signal is transmitted.
Claims14
A communication module comprising:
- a first sub-device connected to a main device;
- and
- at least one second sub-device not connected to the main device but connected to the first sub-device via a first signal line where a clock signal is transmitted, and via a second signal line where a data signal is transmitted,
- wherein the first sub-device is configured to:
- receive, from the main device, a main signal including a command signal, an address signal that identifies an address of at least one register included in at least one second sub-device, and a write data signal to be recorded in a register corresponding to the address, the address signal being a signal subsequent to the command signal and the write data signal being a signal subsequent to the address signal,
- interpret the command signal,
- generate a write instruction signal based on an interpretation result of the command signal after reception of the command signal and during reception of the main signal when information based on the data signal is written in any of the at least one second sub-device,
- generate the data signal based on the interpretation result of the command signal to each of the at least one second sub-device based on the address signal and the write data signal after reception of the command signal and during reception of the main signal, and
- supply the write instruction signal via the first signal line or the second signal line and the data signal via the second signal line to each of the at least one second sub-device after reception of the command signal and during reception of the main signal, and
- wherein each of the at least one second sub-device is configured to:
- determine whether the register corresponding to the address indicated by the address signal is included in the at least one second sub-device, and
- write the write data signal in the register when the register is included in the at least one second sub-device and the write instruction signal is supplied from the first sub-device.
A communication module comprising:
- a first sub-device connected to a main device and configured to receive, from the main device, a main signal including a command signal and a device ID signal indicating a device ID for identifying a device, interpret the command signal, and have first device ID information allocated thereto;
- a second sub-device connected to the first sub-device via a first signal line where a clock signal is transmitted and via a second signal line where a data signal is transmitted to have second device ID information allocated thereto;
- and
- a third sub-device connected to the first sub-device via a third signal line where the clock signal is transmitted and via a fourth signal line where the data signal is transmitted to have third device ID information allocated thereto,
- wherein the first sub-device is configured to:
- determine whether the device ID signal included in the main signal matches the first device ID information the first sub-device has,
- determine whether the device ID signal included in the main signal matches the second device ID information or the third device ID information the first sub-device has,
- when the device ID signal included in the main signal matches the second device ID information the first sub-device has, generate a first sub-device control signal indicating data writing or reading on the second sub-device based on an interpretation result of the command signal,
- supply the first sub-device control signal to the second sub-device,
- when the device ID signal included in the main signal matches the third device ID information the first sub-device has, generate a second sub-device control signal indicating data writing or reading on the third sub-device based on the interpretation result of the command signal, and
- supply the second sub-device control signal to the third sub-device.
