IDSEL
I
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
60
IRDY#
I/O Master device is ready to data transaction
61
TRDY#
I/O Slave device is ready to data transaction
63
DEVSEL# I/O Device select, target is driving to indicate the address is decoded
64
STOP#
I/O Target device request the master device to stop the current transaction
65
PERR#
I/O Data parity error is detected, driven by the agent receiving data
66
SERR#
O/D Address parity error
68
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
92
Clk-run
I/O Clock Run for PCI system. In the normal operation situation, Host should
O/D 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.
