Abstract
There is provided an operating method of a navigation system. The navigation system includes a master device and a slave device connected via a clock line and an SDIO/MOTION line. The operating method includes: setting a data direction of an SDIO/MOTION port of the slave device as an output state upon not receiving a clock signal from the master device via the clock line to be able to output a motion interrupt; and changing the data direction of the SDIO/MOTION port of the slave device to an input state upon receiving the clock signal from the master device via the clock line to be able to receive an address byte; and keeping the data direction at the output state after a data transaction completed.
