12. Pin Types
Description:
The following tables detail the pin types of the PCI 9656AD and PCI 9656BA silicon. The
information in these tables is intended to replace the Pin Type columns of Blue Book
Tables 12-4 through 12-12.
Each table includes 5 columns for each pin:
1. Each entry in the leftmost column contains the name of the signal (or signals, in the case of
multiplexed pins) connected to that pin.
2. Each entry in the next column contains the pin number (or pin numbers in the case of
address buses, data buses, etc. that share the same pin type).
3. Each entry in the next column contains the pin type in the Blue Book.
4. Each entry in the next column contains the actual pin type for the AD silicon revision. Shaded
entries in this column indicate where the actual pin type of the AD silicon differs from the pin
type given in the Blue Book. While these changes should not effect designs that follow the
Blue Book pin types, for designs that use the AD version of silicon, the designers should look
carefully at the shaded entries in this column.
5. Each entry in the rightmost column contains the actual pin type for the BA silicon revision.
Shaded entries in this column indicate where the actual pin type of the BA silicon differs from
the actual pin type of the AD silicon. While these changes should not effect designs intended
to use both AD and BA silicon revisions, for AD designs that are intended to use the BA as a
drop-in replacement for the AD, the designers should look carefully at the shaded entries in
this column.
