11.0 SUBSYSTEM ID AND SUBSYSTEM VENDOR ID
The Subsystem ID and Subsystem Vendor ID registers are con-
figured at PCI Reset time. Immediately after the trailing edge of
PCIRST, the ZR36067 latches the current state on 32 of its input
pins into these registers. Thus, if the system design takes this
into consideration and ensures that the relevant pins are not
being driven by any other device at the trailing edge of PCIRST,
the required states can be assigned to the pins by means of pull-
up or pull-down resistors.
Note: To ensure that the states of the pins are latched correctly,
they must remain stable for at least 3 PCI clock periods after the
trailing edge of PCIRST.
