Pin Function
Broadcast Off – for PHY Address 0
Pull-up = PHY Address 0 is set as an unique PHY address
Pull-down (default) = PHY Address 0 is set as a broadcast PHY address
At the de-assertion of reset, this pin value is latched by the chip.
NAND Tree Mode
Pull-up (default) = Disable
Pull-down = Enable
At the de-assertion of reset, this pin value is latched by the chip.
