     *
     * @description:	The management interface may be configured to be an I 2
     *					C slave. In this mode, an I2 C master has complete program-
     *					ming access to the device's internal control and status registers, including all MIB counters, address lookup tables,
     *					VLAN table and ACL table.
     *					The 7-bit device address is fixed as 1011_111. Because of the fixed address, only one KSZ9477S may be on the I 2 C
     *					bus at a time. The R/W control bit is then appended as the least significant bit to form these 8-bit address/control words:
     *
     *					1011_1110 <write>
     *					1011_1111 <read>
     *
     *					The internal registers and tables of the device are accessed using 16-bit addressing and 8-bit data. The access formats
     *					are as follows:
