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 DP83816 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 DP83816 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.
