2-PORT PCI-TO-PCI BRIDGE
Page 31 of 111
APRIL 2006 – Revision 1.1
Type 0 configuration transactions are issued when the intended target resides on the same
PCI bus as the initiator. A Type 0 configuration transaction is identified by the
configuration command and the lowest two bits of the address set to 00b.
Type 1 configuration transactions are issued when the intended target resides on another
PCI bus, or when a special cycle is to be generated on another PCI bus. A Type 1
configuration command is identified by the configuration command and the lowest two
address bits set to 01b.
The register number is found in both Type 0 and Type 1 formats and gives the DWORD
address of the configuration register to be accessed. The function number is also included
in both Type 0 and Type 1 formats and indicates which function of a multifunction device
is to be accessed. For single-function devices, this value is not decoded. The addresses of
Type 1 configuration transaction include a 5-bit field designating the device number that
identifies the device on the target PCI bus that is to be accessed. In addition, the bus
number in Type 1 transactions specifies the PCI bus to which the transaction is targeted.
3.7.1
TYPE 0 ACCESS TO PI7C8150A
The configuration space is accessed by a Type 0 configuration transaction on the primary
interface. The configuration space cannot be accessed from the secondary bus. The
PI7C8150A responds to a Type 0 configuration transaction by asserting P_DEVSEL_L
when the following conditions are met during the address phase:
The bus command is a configuration read or configuration write transaction.
Lowest two address bits P_AD[1:0] must be 00b.
Signal P_IDSEL must be asserted.
PI7C8150A limits all configuration access to a single DWORD data transfer and returns
target-disconnect with the first data transfer if additional data phases are requested.
Because read transactions to configuration space do not have side effects, all bytes in the
requested DWORD are returned, regardless of the value of the byte enable bits.
Type 0 configuration write and read transactions do not use data buffers; that is, these
transactions are completed immediately, regardless of the state of the data buffers. The
PI7C8150A ignores all Type 0 transactions initiated on the secondary interface.
3.7.2
TYPE 1 TO TYPE 0 CONVERSION
Type 1 configuration transactions are used specifically for device configuration in a
hierarchical PCI bus system. A PCI-to-PCI bridge is the only type of device that should
respond to a Type 1 configuration command. Type 1 configuration commands are used
when the configuration access is intended for a PCI device that resides on a PCI bus other
than the one where the Type 1 transaction is generated.
PI7C8150A performs a Type 1 to Type 0 translation when the Type 1 transaction is
generated on the primary bus and is intended for a device attached directly to the secondary
bus. PI7C8150A must convert the configuration command to a Type 0 format so that the
