This input pin controls the advertised operating mode of the
DP83848H according to the following table. The value on this pin
is set by connecting it to GND (0) or VCC (1) through 2.2 k resis-
tors. This pin should NEVER be connected directly to GND or
VCC.
The value set at this input is latched into the DP83848H at Hard-
ware-Reset.
The float/pull-down status of this pin is latched into the Basic
Mode Control Register and the Auto_Negotiation Advertisement
Register during Hardware-Reset.
The default is 1 since this pin has an internal pull-up.
MII_MODE (RX_DV)
S, O, PD
32
MII MODE SELECT: This strapping option determines the oper-
ating mode of the MAC Data Interface. Default operation (No pul-
lup) will enable normal MII Mode of operation. Strapping
MII_MODE high will cause the device to be in RMII mode of oper-
ation. Since the pin includes an internal pull-down, the default val-
ue is 0.
The following table details the configuration:
LED_CFG (CRS/CRS_DV)
S, O, PU
33
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)
S, O, PU
34
MDIX ENABLE: Default is to enable MDIX. This strapping option
disables Auto-MDIX. An external pull-down will disable Auto-
MDIX mode.
