Abstract
A micro controller unit coupled between a master device and a slave device and including a first communication interface, a serial peripheral interface (SPI) circuit, a switch circuit, a second communication interface, and a switching control circuit is provided. The first communication interface receives a first external signal provided by the master device. The SPI circuit is configured to generate an internal signal. The switch circuit uses a second external signal or the internal signal as an output signal according to a control signal. The second communication interface provides the output signal to the slave device. The switching control circuit generates the control signal according to the level of the first external signal.
