More Information
Summary:A microcontroller and a serial peripheral interface (SPI) system using the same are provided. The SPI system includes a master device and at least one slave device. The slave device is coupled to the master device and configured to communicate with the master device through the SPI. The master device sends one or more of a preset clock signal, an output data signal, and a slave select signal as a clock setting request. The slave device identifies the clock setting request based on the received signal and sends a clock setting data indicating a clock phase and a clock polarity of the slave device in response to the clock setting request. The master device receives the clock setting data and sets the operation mode of the master device to match the clock phase and the clock polarity of the slave device according to the clock setting data.
