LED SELECTOR 2 (PHY_ADDR = 0X1, REG_ADDR = 1CH, SHADOW 01110B)

Write Enable

During a write to this register, setting LED Selector 2 register bit 15 to a 1 allows writing to bits [7:0] of this register. For

reading the values of bits [9:0], perform an MDIO write with bit 15 set to a 0 and preferred shadow values in bits [14:10]. The

next MDIO read of register address 1Ch contains the preferred Shadow register values in bits [9:0].
