APRIL 2006 – Revision 1.1
secondary bus device can respond to it. Type 1 to Type 0 translations are performed only in
the downstream direction; that is, PI7C8150A generates a Type 0 transaction only on the
secondary bus, and never on the primary bus.
PI7C8150A responds to a Type 1 configuration transaction and translates it into a Type 0
transaction on the secondary bus when the following conditions are met during the address
phase:
The lowest two address bits on P_AD[1:0] are 01b.
The bus number in address field P_AD[23:16] is equal to the value in the secondary
bus number register in configuration space.
The bus command on P_CBE[3:0] is a configuration read or configuration write
transaction.
When PI7C8150A translates the Type 1 transaction to a Type 0 transaction on the
secondary interface, it performs the following translations to the address:
Sets the lowest two address bits on S_AD[1:0].
Decodes the device number and drives the bit pattern specified in Table 3-6 on
S_AD[31:16] for the purpose of asserting the device’s IDSEL signal.
Sets S_AD[15:11] to 0.
Leaves unchanged the function number and register number fields.
PI7C8150A 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]. presents the mapping that
PI7C8150A uses.
