Auto-Negotiation Enable: When high, this enables Auto-Negoti-
ation with the capability set by ANO and AN1 pins. When low, this
puts the part into Forced Mode with the capability set by AN0 and
AN1 pins.
AN0 / AN1: These input pins control the forced or advertised op-
erating mode of the DP83848YB according to the following table.
The value on these pins is set by connecting the input pins to
GND (0) or VCC (1) through 2.2 k resistors. These pins should
NEVER be connected directly to GND or VCC.
The value set at this input is latched into the DP83848YB at Hard-
ware-Reset.
The float/pull-down status of these pins are latched into the Basic
Mode Control Register and the Auto_Negotiation Advertisement
Register during Hardware-Reset.
The default is 111 since these pins have internal pull-ups.

MII MODE SELECT: This strapping option pair determines the
operating mode of the MAC Data Interface. Default operation (No
pull-ups) will enable normal MII Mode of operation. Strapping
MII_MODE high will cause the device to be in RMII or SNI mode
of operation, determined by the status of the SNI_MODE strap.
Since the pins include internal pull-downs, the default values are
0.
The following table details the configurations:

LED CONFIGURATION: This strapping option determines the
mode of operation of the LED pins. Default is Mode 1. Mode 1 and
Mode 2 can be controlled via the strap option. All modes are con-
figurable via register access.
SeeTable 3 for LED Mode Selection.
MDIX_EN (RX_ER)

MDIX ENABLE: Default is to enable MDIX. This strapping option
disables Auto-MDIX. An external pull-down will disable Auto-
MDIX mode.
