AN983B

PCI/miPCI Fast Ethernet Controller with integrated PHY

C-BEB3

C-BEB2

C-BEB1

C-BEB0

I/O

Bus command and byte enable

IDSEL

Initialization Device Select. This signal is asserted when host issues the

configuration cycles to the AN983B.

FRAME#

I/O

Begin and duration of bus access, driven by master device

IRDY#

I/O

Master device is ready to data transaction

TRDY#

I/O

Slave device is ready to data transaction

DEVSEL#

I/O

Device select, target is driving to indicate the address is decoded

STOP#

I/O

Target device request the master device to stop the current transaction

PERR#

I/O

Data parity error is detected, driven by the agent receiving data

SERR#

O/D Address parity error

PAR

I/O

Parity, even parity (AD [31:0] + C/BE [3:0]), master drives par for address

and write data phase, target drives par for read data phase

Clk-run

I/O

O/D

Clock Run for PCI system. In the normal operation situation, Host should

assert this signal to indicate AN983B about the normal situation. On the

other hand, when Host will deassert this signal when the clock is going down

to a non-operating frequency. When AN983B recognizes the deasserted

status of clk-run, then it will assert clk-run to request host to maintain the

normal clock operation. When clk-run function is disabled then the AN983B

will set clk-run in tri-state.
