7.1.9 PCI IDSEL
The IDSEL input of each PCI device is connected to one of the PCI
address/data lines for individual addressing in configuration space.
Table XX shows the connection of the IDSEL signal for the various
devices on the BAB 740 and the PMC carrier board.
Table 38: IDSEL Connection
Device
Number
IDSEL Device
0 - MPC106
11 AD(11) W83C553F
13 AD(13) SYM53C860
14 AD(14) 21143
15 AD(15) PMC Slot 0
16 AD(16) PMC Slot 1
30 AD(30) Universe II
Note that the device numbers differ from Intel convention where
number 0 corresponds to AD(11) and number 20 corresponds to
AD(31). Configuration cycles with device number 0 are handled
internally in the MPC106 and therefore don‘t correspond with a
address/data line.
