Programing Details

The overall design of the IPMC712 and IPMC761 is based on the PowerPlus II architecture. The programming characteristics for both modules conforms to the PowerPlusII Programming Specification.

Note The PowerPlus II Programming Specification covers a large variety of programming configurations, many of which are not applicable to either module. This chapter describes those aspects of the specification that are unique to both modules.

PCI Local Bus

The on-board PCI devices on the IPMC712 and the IPMC761 are the PCI-to-ISA Bridge and the SCSI controller.

The PCI-to-ISA Bridge (PIB)

The PCI-to-ISA Bridge (PIB) provides the bridging functions between PCI local bus and the ISA local resource bus. Other features contained in the PIB are:

■8259 Interrupt Controller

■ISA DMA support

■Timers and counters

The SCSI Controller

The SCSI controller’s clock speed is 40 MHz. The presence of the SCSI device can be positively determined by reading the Device ID PCI Configuration Register 0x02 - 0x03. The Device ID is 0x0012.
