The DP83822 can be configured for any of the 32 possible PHY addresses available through bootstrap configuration. The PHY address is latched into the device upon power up or hardware reset. Each DP83822 or port sharing PHY on the serial management bus in the system must have a unique PHY address. The DP83822 supports PHY address strapping values 0x0000 (0b00000) through 0x001F (0b11111).
By default, the DP83822 will latch-in PHY address 0x0001 (0b00001). This address can be changed by adding the required pullup or pulldown resistors defined in the bootstrap section above.
