Management Interface (Optional)

Table 2-4describes the optional signals used by the client to access the management features of the GEMAC core. See “Using the Optional Management Interface,” on page 77.

Table 2-4:Optional Management Interface Signal Pinout

Signal	Direction	Clock	Description
Signal	Direction	Domain	Description
		Domain

host_clk	Input	n/a	Clock for the Management
			Interface; must be 10 MHz or
			above.

host_opcode[1:0]	Input	host_clk	Defines operation to be performed
			over MDIO interface. Bit 1 is also
			used as a read/write control
			signal for configuration register
			access.

host_addr[9:0]	Input	host_clk	Address of register to be accessed.

host_wr_data[31:0]	Input	host_clk	Data to write to register .

host_rd_data[31:0]	Output	host_clk	Data read from register.

host_miim_sel	Input	host_clk	When asserted, the MDIO
			interface is accessed. When not
			asserted, the configuration
			registers are accessed.

host_req	Input	host_clk	Used to signal a transaction on the
			MDIO interface.

host_miim_rdy	Output	host_clk	When high, the MDIO interface
			has completed any pending
			transaction and is ready for a new
			transaction.

MAC Unicast Address (Optional)

Table 2-5describes the alternative method of access to the unicast address registers when the optional Management Interface is not present.

Table 2-5:Optional MAC Unicast Address Signal Pinout

Signal	Direction	Description

mac_unicast_address[47:0]	Input	Used to assess the MAC unicast
		address registers when the
		Management Interface is not used

Note: All bits are registered on input but may be treated as asynchronous inputs.
