[0051]SMI: Serial Management Interface (Serial Management Interface) is a PHY management interface that can be used to read and write PHY registers to control the behavior of the PHY or read the status of the PHY; PHY is a standard module defined in IEEE802.3; The address space of the PHY register is 5 bits, so the register range is 0-31, and there are at most 32 registers; IEEE802.3 defines the functions of the 16 registers with addresses 0-15, and the registers with addresses 16-31 are reserved for chip manufacturing Business freedom definition.
[0052] see figure 1 , figure 1 It is a schematic flowchart of an SMI interface-based all-in-one Ethernet refresh method in an embodiment of the present invention.
[0053] like figure 1 Shown, a kind of all-in-one Ethernet refreshing method based on SMI interface, described method comprises:
[0054] S11: The main chip of the all-in-one device simulates an SMI protocol signal by controlling the behavior of the GPIO interface, w...
