2 Hawk PCI Host Bridge & Multi-Processor Interrupt Controller Endian Conversion Notes 1. “1000” is the default setting. 2. Parking disabled is a test mode only and should not be used, since no one will drive the PCI bus when in an idle state. 3. All other combinations in the PRK setting not specified in the table are invalid and should not be used. A special function is added to the PCI arbiter to hold the grant asserted through a lock cycle. When the “POL” bit in the PCI arbiter control register is set, the grant associated with the agent initiating the lock cycle will be held asserted until the lock cycle is complete. If this bit is clear, the arbiter does not distinguish between lock and non-lock cycle. The PHB supports both big- and little-endian data formats. Since the PCI bus is inherently little-endian, conversion is necessary if all PPC devices are configured for big-endian operation. The PHB may be programmed to perform the endian conversion described below. When PPC Devices are Big-Endian When all PPC devices are operating in big-endian mode, all data to/from the PCI bus must be swapped such that the PCI bus looks big endian from the PPC bus’s perspective. This association is true regardless of whether the transaction originates on the PCI bus or the PPC bus. This is shown in Figure 2-7. 2-38 <strong>Computer</strong> Group Literature Center Web Site

Big-to-Little-Endian Data Swap When PPC Devices are Little Endian DL07-00 Functional Description 1916 9610 When all PPC devices are operating in little-endian mode, the originating address is modified to remove the exclusive-ORing applied by PPC60x processors. Note that no data swapping is performed. http://www.motorola.com/computer/literature 2-39 DL15-08 DL23-16 DL31-24 D0 D1 D2 D3 D4 D5 D6 D7 D7 D6 D5 D4 D3 D2 D1 D0 AD63-56 DH07-00 AD55-48 DH15-08 AD47-40 DH23-16 AD39-32 DH31-24 AD31-24 DL07-00 AD23-16 DL15-08 AD15-08 AD07-00 D0 D1 D2 D3 D4 D5 D6 D7 D7 D6 D5 D4 D3 D2 D1 D0 AD31-24 AD23-16 AD15-08 AD07-00 DL23-16 DL31-24 32-bit PCI PPC Bus 64-bit PCI PPC Bus 2
