port INT for AR8035

Post by Daniil96Let »

#xCORE-200 eXplorer
#AN00199 Gigabit Ethernet

Existing ports that can be modified:
>>port p_smi_mdio = on tile[1]: XS1_PORT_1C;
>>port p_smi_mdc = on tile[1]: XS1_PORT_1D;
>>port p_eth_reset = on tile[1]: XS1_PORT_1N;
Existing ports that cannot be changed:
>>rgmii_ports_t rgmii_ports = on tile[1]: RGMII_PORTS_INITIALIZER;

Question where port INT belongs?
I didn't find where it is described, but I would like to reconfigure it.

From a quick review, according to section 2.4 of the AN00199, the driver code for this Gigabit PHY is operating in a timer enabled polling mode.

That is, the INT line does not look to being used.
