IXP1200 Network Processor
PCI Arbitration and Central Function Support
The IXP1200 contains an optional arbiter to support up to three PCI Bus masters. This includes the
IXP1200 plus two external PCI Bus master devices. The external masters are supported by two
request signals, REQ#[1:0], and two grant signals GNT#[1:0].
The IXP1200 can also provide PCI Central Function support. In this configuration, the IXP1200:
Two configuration pins, PCI_CFN[1:0], are sampled at the rising edge of RESET_IN# to
determine the PCI configuration (see
Device Reset
The IXP1200 can be reset by the following:

Provides Bus Parking where the IXP1200 is the default PCI Bus master, and it drives valid
logic levels on the PCI A/D, C/BE, and PAR pins during reset and idle PCI Bus conditions.
