It is also a 7-ports switch with +5 giga embedded phys, 2 cpu ports, and the same MAC logic of MT7530. Cpu +port 6 only supports SGMII interface. Cpu port 5 supports either RGMII +or SGMII in different HW sku, but cannot be muxed to PHY of port 0/4 like +mt7530. Due to SGMII interface support, pll, and pad setting are different +from MT7530.
