Abstract
A first slave device and a second slave device to which different slave identifiers are added are connected to a serial bus. The second slave device includes a second storage unit including multiple registers and a second serial interface unit that receives a command in which the slave identifier of the second slave device is set via the serial bus and that sets a result of a process corresponding to the received command in at least one register in the second storage unit.

A communication module comprising:
- a first slave device and a second slave device which are connected to a serial bus and to which different slave identifiers are added,
- wherein the second slave device comprises:
- a second storage comprising a plurality of registers, and
- a second serial interface configured to receive a second command in which the slave identifier of the second slave device is set via the serial bus and that sets a result of a process corresponding to the received second command in at least one register in the second storage,
- wherein the first slave device comprises:
- a first storage comprising a plurality of registers,
- a second sub storage comprising at least one register,
- a first serial interface configured to receive a first command in which the slave identifier of the first slave device is set via the serial bus and that sets a result of a process corresponding to the received first command in at least one register in the first storage, and
- a second sub serial interface configured to receive a second sub command in which the slave identifier of the second slave device is set via the serial bus and that sets a result of a process corresponding to the received command in the at least one register in the second sub storage,
- wherein the second serial interface is configured to detect any command reception error and, upon detection of the reception error, is configured to not set the value of the register in the second storage, which corresponds to the command in which the reception error is detected, and
- wherein the second sub serial interface is configured to detect any command reception error and, upon detection of the reception error, is configured to not set the value of the second sub register in the second sub storage, which corresponds to the command in which the reception error is detected.
