Abstract
A master device and slave devices are connected with each other through an SDA and an SCL, and at least one of a serial communication data signal communicated through the SDA and a serial communication clock signal communicated through the SCL is latched with use of a noise removal clock signal whose frequency is higher than that of the serial communication clock signal, and is taken in.
Claims13
A serial data communication method with use of a data line and a clock line, comprising the steps of:
- latching at least one of a data signal communicated through the data line and a clock signal communicated through the clock line, the latching being carried out with use of a signal whose frequency is higher than that of the clock signal;
- and
- taking in the at least one of the data signal and the clock signal.
A serial data communication device, in which a master device and a slave device are connected to each other with use of at least a data line and a clock line, the serial data communication device comprising
- a noise removal section for latching at least one of a data signal communicated through the data line and a clock signal communicated through the clock line, the latching being carried out with use of a second clock signal whose frequency is higher than that of the clock signal, and taking in the at least one of the data signal and the clock signal.
