Slave Configuration Transfers
The host can access the PCnet-PCI PCI configuration
space with a configuration read or write command. The
PCnet-PCI controller will assert
DEVSEL
if the IDSEL
input is asserted during the address phase and if the ac-
cess is a configuration cycle.
DEVSEL
is asserted two
clock cycles after the host has asserted
FRAME
. All
configuration cycles are of fixed length. The PCnet-PCI
controller will assert
TRDY
on the 3rd clock of the
dataphase.
Slave Configuration Read
The Slave Configuration Read command is used by the
host CPU to read the configuration space in the PCnet-
PCI controller. This provides the host CPU with informa-
tion concerning the device and its capabilities. This is a
single cycle, non-burst 8-bit, 16-bit, or 32-bit transfer.
