!
Decodes the device number and drives the bit pattern specified in Table 4-6 on
S1_AD[31:16] or S2_AD[31:16] for the purpose of asserting the device’s IDSEL
signal.
!
Sets S1_AD[15:11] or S2_AD[15:11] to 0.
!
Leaves unchanged the function number and register number fields.
PI7C7300A asserts a unique address line based on the device number. These address
lines may be used as secondary bus IDSEL signals. The mapping of the address lines
depends on the device number in the Type 1 address bits P_AD[15:11]. Table 4-6
presents the mapping that PI7C7300A uses.

PI7C7300A can assert up to 16 unique address lines to be used as IDSEL signals for up
to 16 devices on the secondary bus, for device numbers ranging from 0 through 15.
Because of electrical loading constraints of the PCI bus, more than 16 IDSEL signals
should not be necessary. However, if device numbers greater than 15 are desired, some
external method of generating IDSEL lines must be used, and no upper address bits are
then asserted. The configuration transaction is still translated and passed from the
primary bus to the secondary bus. If no IDSEL pin is asserted to a secondary device, the
transaction ends in a master abort.
PI7C7300A forwards Type 1 to Type 0 configuration read or write transactions as
delayed transactions. Type 1 to Type 0 configuration read or write transactions are
limited to a single 32-bit data transfer.
4.8.3
TYPE 1 TO TYPE 1 FORWARDING
Type 1 to Type 1 transaction forwarding provides a hierarchical configuration
mechanism when two or more levels of PCI-to-PCI bridges are used.
