[0023] Furthermore, the processor is connected to the BIOS Flash via an SPI interface.

[0024] Furthermore, during the boot process, different numbers displayed on the digital tube correspond to different startup stages.

[0025] Furthermore, the device implements startup fault diagnosis in the following manner:

[0026] S1, power on and start;

[0027] S2, the processor outputs corresponding debugging information;

[0028] S3, the single chip microcomputer receives debugging information;
