Transmit Data: Differential common output driver. This differential
common output is configurable to either 10BASE-T or 100BASE-TX
signaling:
10BASE-T: Transmission of Manchester encoded 10BASE-T packet
data as well as Link Pulses (including Fast Link Pulses for Auto-
Negotiation purposes).
100BASE-TX: Transmission of ANSI X3T12 compliant MLT-3 data.
The DP83815 will automatically configure this common output driver
for the proper signal type as a result of either forced configuration or
Auto-Negotiation.
Receive Data: Differential common input buffer. This differential
common input can be configured to accept either 100BASE-TX or
10BASE-T signaling:
10BASE-T: Reception of Manchester encoded 10BASE-T packet
data as well as normal Link Pulses and Fast Link Pulses for Auto-
Negotiation purposes.
100BASE-TX: Reception of ANSI X3T12 compliant scrambled MLT-3
data.
The DP83815 will automatically configure this common input buffer
to accept the proper signal type as a result of either forced
configuration or Auto-Negotiation.

BIOS ROM/Flash Chip Select: During a BIOS ROM/Flash
access, this signal is used to select the ROM device.
BIOS ROM/Flash Data Bus: During a BIOS ROM/Flash access
these signals are used to transfer data to or from the ROM/Flash
device.
MD[5:0] pins have internal weak pull ups.
MD6 and MD7 pins have internal weak pull downs.
BIOS ROM/Flash Address: During a BIOS ROM/Flash access,
these signals are used to drive the ROM/Flash address.
BIOS ROM/Flash Write: During a BIOS ROM/Flash access, this
signal is used to enable data to be written to the Flash device.
BIOS ROM/Flash Read: During a BIOS ROM/Flash access, this
signal is used to enable data to be read from the Flash device.
