  • Publication number: 20200401548
    Abstract: An embedded controller connected with a main control module through a first interface module is connected with an SPI storage through a second interface module. The main control module outputs SPI bus commands to an SPI storage through the embedded controller. The embedded controller includes an EC FW block and an SPI bus command filter module. The EC FW block stores at least one limited SPI bus command. The SPI bus command filter module can switch between an enable mode and a disable mode. In the enable mode, the SPI bus command filter module filters out the SPI bus command from the main control module based on the at least one limited SPI bus command, and blocks the SPI bus command, thus performing a write protection of the SPI storage.
