An asterisk (*) at the end of a pin name indicates an active-low signal that is a general-
interface for the PD6729.
Pins marked with a dagger (†) in the pin description tables can be switched between CMOS
and TTL input levels when CORE_VDD is powered at 5 volts. All other pins use CMOS input
levels when CORE_VDD is powered at 5 volts and TTL input levels when powered at 3.3
volts.
A pin name ending in bracketed digits separated by a colon [n:n] indicates a multi-pin bus.
The pin number (Pin Number) column indicates the package pin that carries the listed signal.
Note that multi-pin buses are listed with the first pin number corresponding to the most-
significant bit of the bus. For example, pin numbers 4-5, 7-12, 16-20, 22-24, 38-43, 45-46, 48-
49, 51-55, and 57 associated with PCI Bus Address Input and Data Input/Output pins
AD[31:0] indicate that:
The quantity (Qty.) column indicates the number of pins used (per socket where applicable).
The I/O-type code (I/O) column indicates the input and output configurations of the pins on
the PD6729. The possible types are defined below.
The power-type code (Pwr.) column indicates the output drive power source for an output pin
or the pull-up power source for an input pin on the PD6729. The possible types are defined
below.
