3.4.7 PCI interfaces
There are three standard PCI slots available on the CB1051.
N
OTE
Please note that due to the nature of the PCI bus some signals in the following table are different from
one PCI slot to the other. This applies to the test signals (A4, B4), the interrupt signals (A6, A7, B7, B8),
the clock signal (B16), the grant signal (A17), the request signal (B18), and the ID-select signal (A26).
